What are the factors of 121?

Factors are the numbers that help us divide things equally without any leftovers. In this topic we will learn about factors of 121. The number has both positive and negative integers that divide 121 without leaving any remainder.

How to find the factors of 121?

Factors help us divide numbers equally, making calculations faster and easier. Few methods used for calculating factors are as follows

Multiplication Method

In this method a pair of number is multiplied to get the resultant.

1×121=121

11×11=121, 1, 11, 121 are the factors of 121

Division Method

In this method, we start dividing numbers from 1 to get 0 remainder.

121 1=121

121 11=11

So the factors are 1,11 and 121.

Prime Factorization

The breaking down of numbers as prime factors is called prime factorization. The factors of 121 are:
121=11 × 11= 11²

Factor tree method

A factor tree shows how a number can be parted down into prime factors.121 is broken down into two factors, 11 and 11.

Positive and negative pairs

Both positive and negative factors constitute a number

Positive :(1,11,121)

Negative:(-1,-11,-121)
