## What are the factors of 117

A factor of a number is a number that can divide the given number evenly without any decimal points in the quotient and with zero remainders. So, for example, the factors of 12 are 1, 2, 3, 4, 6, and 12, because all of those numbers can evenly divide the number 12.

To find the factors of 117, we can start by dividing 117 by 2. If 117 is evenly divisible by 2, then 2 is a factor of 117. If 117 is not evenly divisible by 2, then we can try dividing it by 3, and so on.

Here’s how it would work:

- 117 / 2 = 58.5 (not evenly divisible)
- 117 / 3 = 39 (not evenly divisible)
- 117 / 4 = 29.25 (not evenly divisible)
- 117 / 5 = 23.4 (not evenly divisible)

We can keep going like this until we find a number that 117 is evenly divisible by a number. But if we keep going, we will eventually find that 117 is evenly divisible by 1 and 117. So, the factors of 117 are 1 and 117.

## How to Find Factors of 117

The most prominent methods of finding the factors of a number are as given below and they can be used to find the factors of 117 also.

- Factor of 117 using Multiplication Method
- Factors of 117 using Division Method
- Prime Factorization of 117
- Factor tree of 117

## Factors of 117 using Multiplication Method

To find the factors of 117 using the multiplication method, we can create a list of pairs of numbers whose product is 117. The factors of 117 will be the numbers in each pair.

For example, here are all the pairs of numbers whose product is 117:

1 x 117 = 117

3 x 39 = 117

9 x 13 = 117

So, the factors of 117 are 1, 3, 9, 13, and 117.

## Factors of 117 Using Division Method

To find the factors of 117 using the division method, we can start by dividing 117 by 2. If 117 is evenly divisible by 2, then 2 is a factor of 117. If 117 is not evenly divisible by 2, then we can try dividing it by 3, and so on.

Here’s how it would work:

- 117 / 2 = 58.5 (not evenly divisible)
- 117 / 3 = 39 (not evenly divisible)
- 117 / 4 = 29.25 (not evenly divisible)
- 117 / 5 = 23.4 (not evenly divisible)

We can keep going like this until we find a number that 117 is evenly divisible by. But if we keep going, we will eventually find that 117 is evenly divisible by 1 and 117. So, the factors of 117 are 1 and 117.

In prime factorization, we try to express a number as a product of its prime factors. A prime number is a number that is only divisible by 1 and itself. For example, the first few prime numbers are 2, 3, 5, 7, 11, and 13.

To find the prime factorization of 117, we can start by dividing 117 by the smallest prime number, which is 2. If 117 is evenly divisible by 2, then we can divide it by 2 again and again until we get a number that is not evenly divisible by 2.

Here’s how it would work:

- 117 / 2 = 58.5 (not evenly divisible). Since 117 is not evenly divisible by 2, we move on to the next smallest prime number, which is 3.
- 117 / 3 = 39 (not evenly divisible). Again, 117 is not evenly divisible by 3, so we move on to the next smallest prime number, which is 5.
- 117 / 5 = 23.4 (not evenly divisible). Since 117 is not evenly divisible by 5, we move on to the next smallest prime number, which is 7.
- 117 / 7 = 16.7 (not evenly divisible). Since 117 is not evenly divisible by 7, we move on to the next smallest prime number, which is 11.
- 117 / 11 = 10.63 (not evenly divisible). Since 117 is not evenly divisible by 11, we move on to the next smallest prime number, which is 13.
- 117 / 13 = 9 (evenly divisible). Since 117 is evenly divisible by 13, we can divide 117 by 13 again to get 9.
- 9 / 13 = 0.69 (not evenly divisible). Since 9 is not evenly divisible by 13, we are done.

Therefore, the prime factorization of 117 is 13 x 9, or 13 x 3^2. This means that the prime factors of 117 are 13 and 3, and 3 appears twice in the prime factorization.

## Factor tree of 117

To create a factor tree for 117, we can start by finding two factors of 117 whose product is 117. For example, we can find that 9 and 13 are both factors of 117 because 9 x 13 = 117.

Next, we can find two factors of 9 whose product is 9. For example, we can find that 3 and 3 are both factors of 9 because 3 x 3 = 9.

Finally, we can create a tree-like diagram to represent the factors of 117. It would look like this:

## Factor Pairs of 117

Calculate Pair Factors of

1 x 117=117

3 x 39=117

9 x 13=117

13 x 9=117

39 x 3=117

So Pair Factors of 117 are

(1,117)

(3,39)

(9,13)

(13,9)

(39,3)

The factor pairs of 117 are all the pairs of numbers that can be multiplied together to equal 117. For example, the factors pairs of 117 are (1, 117), (3, 39), and (9, 13).

We can find all the factor pairs of 117 by dividing 117 by every number between 1 and 117. If 117 is evenly divisible by a number, then that number and 117 divided by that number are both factors of 117.

For example, if we divide 117 by 2, we get 58.5, which is not a whole number. So, 2 is not a factor of 117. If we divide 117 by 3, we get 39, which is also not a whole number. So, 3 is not a factor of 117.

We can keep going like this until we find all the factor pairs of 117. In total, there are 3 factor pairs of 117: (1, 117), (3, 39), and (9, 13).

## Frequently Asked Questions on Factors of 117

**What are the factors of 117?**

The factors of 117 are 1, 3, 39, and 117.

**How many factors does 117 have?**

117 has 4 factors; 1, 3, 39, and 117.

**Is 117 a prime number? **

No, 117 is not a prime number since it has more than two distinct factors.

**What are the common factors of 117?**

The common factors of 117 are 1 and 3.

**Is one a factor of 117?**

Yes, one is a factor of 117 since any number divided by one will result in that same exact number (117).

**How do you find the factors of 117?**

You can find the factors of 117 by first listing out all its divisors starting with one and ending at itself (117). Then check each divisor to see if it divides into other numbers or not (For example; checking if 3 divides into 39 or not). Once you’ve checked all numbers you’ll know the exact amount and value of each factor for that particular number (117).

**Are there any negative factors for the number 117?**

No, there are no negative factors for the number 117 as any factor multiplied by a negative will result in a negative value which cannot be factored from this positive integer (117).

**What is an example of using the greatest common factor to find the GCF for two numbers including 1197?**

To find the greatest common factor between two integers using 1197 as an example; first list out all its divisors starting with one and ending at itself (1197), then repeat this process for your other integer (for example; finding all possible divisors from 1208) then compare these two sets to look for overlaps between them both to determine what’s they’re greatest common factor because those will be shared between them both minus any others which may have been found by either set independently but not as part of their combined pair containing 1197 & 1208 in our example case here today!

**What is an example of using prime factorization to solve 1197?**

To use prime factorization with 1197 as an example; start off by dividing it down until it can’t be divided anymore while keeping track the entire time on paper or digitally whichever works best for you along with writing down which primes were used in process here to minimize overall time spent factoring larger numbers like ours today – once done take those same primes used in order from least to greatest placing them together now as our final product thus having finished our usage correctly!

**Could we divide some other numbers into 1197 besides its own four listed above (1,3,39 & 177)?**

No, none other than these four listed can be divided from within this specific number here today due to it being composite so even attempting to attempt further division would only lead nowhere else further wasting your valuable moments!
