Find the greatest common factor of the following terms.
10g5h2, 40g3h4, 55g3h2
Step 1 of 3
Determine the greatest common numerical factor of every coefficient.
You can use the list of factors of each number to find their greatest common factor, or GCF.
factors of 10: 1, 2, 5, 10
factors of 40: 1, 2, 4, 5, 8, 10, 20, 40
factors of 55: 1, 5, 11, 55
What is the GCF of 10, 40, and 55?
5
Note that this gives you the numerical factor in the GCF of the terms.
Step 2 of 3
Determine the greatest common variable factor of every term by finding the smallest exponent of each variable.
Term Exponent of g Exponent of h
95h2
93h4
