Question

What is the greatest common factor of 12a and 9a2

Answer 1

GCF is 3a

Explanation:

I just know LOLLL

Answer 2

For these types of problems, You must look at the coefficients and variables separately and find the GCF for each. Then, combine the two

First, take 12 and 9

Factors of both

9- 1, 3, 9

12- 1, 2, 3, 4, 6, 12

So the gcf of 12 and 9 is 3

Now do the variables a and a^2

a^2 is just a twice

The GCF is a

Now combine a and 3

Answer: GCF is 3a
