## What is GCF in math example?

The greatest common factor (GCF) of a set of numbers is the largest factor that all the numbers share.

For example, 12, 20, and 24 have two common factors: 2 and 4.

The largest is 4, so we say that the GCF of 12, 20, and 24 is 4.

GCF is often used to find common denominators.
