Factors are the numbers that divide another number equally, without leaving any remainder. When you multiply two numbers to find another number, the two which are multiplied are factors. You can think of factors as the building blocks that will help you make numbers.

What are the factors of 151?

Factors are the numbers that help us divide things equally without any leftovers. Factors of 151 are 1 and 151 as 151 is a prime number. The number has both positive and negative integers that divide 151 without leaving any remainder.

How to find the factors of 151?

Factors help us divide numbers equally, making calculations faster and easier. Given below are the methods used to find factors:

Finding Factors Using Multiplication

In this method, we take two numbers and find the product of those two numbers to get the required number.

Example: 1×151=151, this means that 1 and 151 are the factors of 151.

Finding Factors by Division Method

We divide 151 by numbers starting from 1 and see which number gives the remainder of 0.

151 1=151

151 151=1

So the factors are 1 and 151.

Prime Factors and Prime Factorization

The breaking down of numbers as prime factors is called prime factorization. As 151 is a prime number, it can have only two factors. So, it cannot be divided into smaller parts.

Factor tree

A factor tree shows how a number can be parted down into prime factors.151 cannot be broken down into two factors, as it is a prime number.

Positive and negative pairs

The factors of a number will have both the positive and negative numbers:

Positive :(1,151)

Negative:(-1,-151)
