Usually, you are given two numbers like 30 and 42. Then you are asked to list the factors they share (have in common). That answer is 1, 2, 3 and 6. You might be asked for the largest (greatest) of these. The GCF is 6.

All numbers have factors. Some numbers have some of the same factors as other numbers. These are known as common factors. Since 6 and 9 both have 3 as a factor, they share a common factor.
