How do you get the greatest common factor of 6a^2b + 18ab^3
-------------
1st, common with what? Only one binomial expression is given.
If you mean common between 6a^2b AND 18ab^3, then:
-----------------
By inspection.
If both coefficients are even, divide by 2.
--> 3a^2b, 9ab^3
Now one is odd, so you can't do that again.
Both have a factor of a, so divide by a:
--> 3ab, 9b^3
Both have a b:
--> 3a, 9b^2
Both have a 3:
--> a, 3b^2
------------------
You factor out all common factors, either one at a time or together.

I didn't work it for you, I don't need the practice.
