Factorization or factoring consists of writing a number or another mathematical object as a product of several factors.

We use factorization to perform arithmetic operations. Whereby we group the factors so that it is easier for us to multiply.

We also use factorization is to find the least common multiple and greatest common divisor.

**Formula to factorize a number.**

Factoring integers is pretty simple. You begin by ;

- Dividing the number starting with two and work your way up.

You should know that any quotient that does not have a remainder means that both the divisor and the quotient are factors of that number.

**Example:**

Suppose you are asked to factorize 20.

Your solution will be as follows, using the factoring tree.

Therefore, the factors of 20 are 2, 2, 5 and 1. This means that if you multiply these numbers you will get 20.
