## What are the factors of 158

People often are puzzled when they hear the words “factors” and “factorization”, but it’s actually quite simple. A factor of a number is any integer (like 1, 2 or 79) that you can multiply together to get the original number – 158 in this case! If we take all these factors out for a spin, there will be 6 altogether: 1 x 158 =158; 2 X 79=158; 4 X 39=156, etc.. But hold on – did you know that not every whole numerical value like this one can have only two numbers as its factors? Yep – if those two numbers happen to both be ‘1’, then guess what kind of number we’ve got here?! That’s right–it’s called a prime number! However, in our case with 158, it doesn’t work—which means we need more than just one pair of integers multiplied by each other (in fact-four pairs!) And since after trying different combinations none gave us back “2×79”, we were able to call our final result —a composite.

## How to Find Factors of 158

The main methods through which we can find the factors of 158 are as follows:

- Factor of 124 using Multiplication Method
- Factors of 124 using Division Method
- Prime Factorization of 124
- Factor tree of 124

## Factors of 158 using Multiplication Method

Let’s use the number 158 to see how the Multiplication Method works. The way this method works is by finding two numbers that when multiplied together equal 158. An example would be 1 and 158, or 2 and 79 which both multiply out to give us exactly 159! So for our number of 158, we have factor pairs (1,158) and (2,79). In other words, if you took one from each pair – like 1 plus 79 – it adds up to get you back your original total of 158 again!

## Factors of 158 Using Division Method

Have you ever wondered what the factors of a number are? Factors are special numbers that can be multiplied together to create other numbers. For example, if we multiply 2 and 79, our total is 158! To find all the possible factors for any given number using Division Method, start by dividing it by 1 then move up towards the square root (a special type of number – like 8 or 9) one at a time until there’s no remainder left when divided.

- Let’s try this out with 158 as an example: When we divide 158 by 1 resulting in nothing left over; so 1 is a factor.
- Divide again with 2 leading us to nothing remaining so two also must be assumed as a factor- the same goes on till reaching sqrt(158).
- This way eventually will tell us four different numbers which have been served by multiplying them –it gives us: 1 x2x79x158= 159!

Have you ever wondered how to find out the prime numbers that make up any given number? When it comes to understanding the prime factorization of 158, this is a process where we can break down one large number into smaller ones. Let’s say for example your teacher gave you the number 158 and asked “what are all its component parts?” To answer this question, first, take a look at 2 – remember when it comes to reviewing primes; these are always divisible by themselves only! – See if dividing two will result in an even remainder: in other words divide 158 /2 = 79 – since there is not another whole fraction here (the quotient), then use ‘2’ as our starting point with solving 159s components. By doing so ‘158’, becomes equal to 2×79! So there you have it- The Prime Factorization Of 168 is simply made up of just two primes which multiplied together equals our sought-after total amount: 2 x 79 = 148.

## Factor tree of 158

Factor trees are a fun and helpful way to find the prime factorization of any number. For example, if you wanted to figure out what 158 can be broken down into, here’s how:

First write 158 at the top of your tree. Then draw two branches coming off from it and on each branch write one number that evenly divides into 158 – which is 2 & 79! Now since 79 is already a Prime Number (meaning only itself will divide into it) then there’s nothing more we need to do for this side! So altogether our Factor Tree looks like this…

158

/ \

2 79

This means our result is…158 =2 x79

## Factor Pairs of 158

Calculate Pair Factors of

1 x 158=158

2 x 79=158

79 x 2=158

So Pair Factors of 158 are

(1,158)

(2,79)

(79,2)

To find the factor pairs of 158, we can break it into smaller steps. First, divide 158 by each number from 1 to the square root of that same number (in this case, 12.64). If when you do so there is no remainder left over then that pair is a factor! An example would be if you divided 158 by 2 – it will give 79 as an answer and 0 for a remainder meaning (2,79) is one set of factors for 158. And even though these two numbers are reversed like in with (79,2), they still count because all sets show how 158 can be broken down into other whole numbers! The three distinct factor pairs for 158 are: (1, 158),(2, 79 ), and(79, 2 ).

## Fun Facts of Factors of 158

- 158 is a very special number! It has something called “prime factorization” which means that it can be written as the product of two or more prime numbers. For example, 158 equals 2×79 – and no matter how you combine those primes together to get 158, it will always equal the same amount!

- 158 also has 6 factors in total: 1 (which we call “unit”), 2, 79,158 itself plus one extra 158 so altogether 558. The sum of all these factors is known as its ‘aliquot sum’ which makes 240 – this figure must always be larger than our original number.
