Question

What is the GCF of 18a^2b^2 - 6ab^2 + 12ab^3?

Answer 1

6ab^2

Answer 2

6 is common from numbers.

and ab^2 is common from the variables.

SO:

6ab^2.

Answer 3

Actually, because there is at least b^2 in each term

Answer 4

right.

Answer 5

The GCF is simply the greatest thing the terms share and that you can therefore factor out. Factoring out 6ab^2 we get 6ab^2(3a - 1 + 2b). We can see that there is nothing more that can be factored out of 3a - 1 + 2b.
