Since contain both numbers and variables, there are two steps to find the GCF (HCF). Find GCF for the numeric part then find GCF for the variable part.

Steps to find the GCF for :

1. Find the GCF for the numerical part

2. Find the GCF for the variable part

3. Multiply the values together

Find the common factors for the numerical part:

The factors for are all numbers between and , which divide evenly.

Check numbers between and

Find the factor pairs of where .

List the factors for .
