## Finding Factors

Factors are simply numbers that you multiply together to make another number (a product). In other words they are numbers that can divide evenly into a number.

Numbers that have no factors other than 1 and the number itself are called prime numbers.

factor x factor = product

A good rule when looking for factors is to start with the smallest numbers and work your way up to find all the factors of a number.

**Example**: find the factors of 12

1 x 12 = 12

2 x 6 = 12

3 x 4 = 12

So the factors of 12 are: **1**, **2**, **3**, **4**, **6** and **12**

To find the common factors of two numbers simply list the factors of each and find what they have in common!
