<PRE><B>Question 54530</B>
12a^3b^2,18a^2b^3,6a^4b^4
6 takes care of the coefficients because it is the largest number that
divides 12, 18 and 6 evenly.
Look at the a^3, a^2, a^4
What is the largest power of a that divided these evenly?
It is a^2
Similarly b^2 is the largest that divides b^2,b^3, and b^4.
So the GCF is 6a^2b^2
