## What are the factors of 157

157 is a special kind of number called a prime. This means that it has two secret ingredients in its recipe: 1 and itself! It’s like the only dessert at an ice cream shop – there are no other flavors to choose from, so it must be eaten on its own. Because 157 can’t be separated into any additional numbers, you know those two factors (1 and 157) will always add up to equal this unique number. They’re the perfect combination for making something as awesome as 157!

## How to Find Factors of 157

The major ways through which you can find the factors of 157 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 157 using Multiplication Method

Did you know that 157 is a special number? A prime, to be exact! That means it can’t be made by multiplying any two other numbers together. In fact, the only way to make 157 with multiplication is by taking our smallest number (1) and then multiplying it by itself: 1 x 157 =157! So if we’re looking for factor pairs of this prime using just multiplication, all we have are these 2 magical numbers – 1 &  157.

## Factors of 157 Using Division Method

Prime numbers are very special and unique — they can only be divided by 1 or themselves. That’s why 157, a prime number, is so easily recognizable! If we take the division method to figure out all of its factors (the way you divide something in two), then the answer will always just be 1 and itself: I like to think that means each one stands alone as an individual kingdom unto itself!

Prime numbers is a special kind of number because they can only be divided by themselves and the number 1. For example, take 157 – it’s a prime number so its prime factorization is simply 157! That means that we cannot write down any other factors for this particular number since it doesn’t have them; if you divide 157 by anything else besides itself or 1, you won’t get an even answer. This makes our lives easier when multiplying two large numbers together as long as one of those two is prime!

## Factor tree of 157

Have you ever tried to build a tree out of numbers? Well, when it comes to prime numbers like 157 they don’t need any more divisions and so we can’t make them into factor trees! A factor tree is an amazing tool that helps us figure out what makes up our number by dividing the bigger parts until all pieces are prime.
For instance, if I were trying to find the factors for 156 then after some division my factoring tree would look something like this:

156 χ 2 = 78; 78 ÷ 2 = 39; 39 Χ 3 13; 13 X3=39. So in total 156 has two sets of factors- (2 x 78) & (3Χ13).

Prime Numbers have a special quality that makes them unique from other numbers. 157 is one example of these, and it’s the only number with two factors: 1 & 157 (and their reverse pair). A factor pair is simply 2 numbers that multiplied together give you the original number – in this case, it’d be 1 x 157 =157!

## Fun Facts of Factors of 157

• 157 is an interesting prime number! It’s the first one of a special type – 8n + 5. That means it can be written as 8 x some other number plus 5, putting in any whole numbers you like. If we pick 25 for that “some other number,” then 157 = (8×25) +5  or 200+57=157!
•  Amazingly enough, this single result works out two different ways so that 157 equals both 11 and 59 added to different higher numbers — 213 and 219 respectively.
• Even more impressively, when used 156 & 12 together in a Pythagorean Triple Formula measuring triangle sides with rational lengths each time, again they always add up to form the same unique 157 value every single time too!
• And if all those facts weren’t already noticing-worthy on their own here’s another fun fact about this Prime Number: Unlike some Palindromic Primes where its digits read identical whether forwards or backward – such as 101 which spells ‘101′ either way — no matter how many times you try rearranging these three specific digits 1, 4, 7, it will never spell ‘157’, neither forward nor backward.

## Examples of Factor of 157

1) Samantha had 157 pieces of candy. She wants to divide them evenly between 3 people. How many pieces will each person get?
