## What are the factors of 142

142 is not a prime number, meaning that it can be broken down into several smaller numbers. To find these factors of 142, we look to its prime factorization: 2 * 3 * 23. By multiplying the three prime factors together (2 x 3 x 23), you get your original starting point -142! All nine positive integer factors are 1, 2 ,3 ,6 9 18 47 94 and 142.

## How to Find Factors of 142

The main methods through which the factors of a number can be found are given below and those same methods can be used to find the factors of 142.

- Factor of 142 using Multiplication Method
- Factors of 142 using Division Method
- Prime Factorization of 142
- Factor tree of 142

## Factors of 142 using Multiplication Method

To factor the number 142, you can use a simple process of multiplication. Start by selecting two factors from 1 to 142 (1 and 142 in this case). Multiply these numbers together; if their product equals your target number, then congratulations! You have found one pair of factors – in our example, that would be (1 x 142 =142)! Repeat with different pairs until the final result is equal to your original value- here that’s still 42. With some patience and math skills, you will find all possible sets of solutions for any given integer!

## Factors of 142 Using Division Method

To easily identify the factors of any number, follow these steps: start with your target and divide it by 1. If the resulting answer is even, then you have a factor! Move on to dividing that same number by 2; if this division remains even – congrats on another factor for your list! Keep going until repeating numbers or reaching what was initially inputted appears. For example – to find all the factors from 142 one would obtain 1, 2, 3, 6, 9, 18, 47 94, and finally hit back at our original integer again:142

Breaking down a number into its prime factors is the process of finding out which smaller numbers were used to create that larger one. For example, 142 was created by combining 2 and 3 together and then multiplying it with 23; meaning there’s no other combination than this specific one (2*3*23) that would get you back the same exact result! Every number has its own unique factorization based on what primes make it up – so once we know all these primes in their correct configuration, they can’t be swapped around or changed otherwise you wouldn’t have your original target value anymore!

## Factor tree of 142

To determine the prime factorization of a number, like 142 in this example, you can create what is called a Factor Tree. Begin by writing the target number at the top of your tree and then divide it into its smallest prime factors from there. Continue to branch out until each segment has been reduced down to prime numbers- these are referred to as ‘leaves.’ The combination of all leaves found within your Factor Tree will give you an answer that reflects how many times those particular primes multiplied together equals your original input! For instance, 142 = 2 * 3 * 23 when composed through our hypothetical Factor Tree here which therefore gives us our final result: Prime Number Factoring for 142 equals (2 x 3 x 23).

## Factor Pairs of 142

Calculate Pair Factors of

1 x 142=142

2 x 71=142

71 x 2=142

So Pair Factors of 142 are

(1,142)

(2,71)

(71,2)

The factor pairs of 142 are the combinations of positive integers that can be multiplied together to equal this number. In total, there are 11 different possible sets consisting of a numerator and denominator or both; for example (1,142), (2, 71) etc.. For each pair these numbers when individually multiplied create an answer which is exactly 142.

## Fun Facts of Factors of 142

- 142 may not be a prime number, but it is still an interesting one. It can’t be expressed as the product of two equal integers – that rules out perfect squares – and instead has nine different positive integer factors when factored according to its prime factorization: 2 * 3 * 23. Moreover, 142 is even since it’s divisible by two; however, unlike other numbers in certain patterns such as multiples or powers of three or five (such as 30 = 5*6), 142 doesn’t work with these ratios either!
