For this case we have by definition, that the Greatest Common Factor or GFC, of two or more whole numbers is the largest integer that divides them without leaving a residue.

Now, we look for the factors of 72 and 210:

72: 1,2,3,4,6,8,9,12,16,24,36,72

210: 1,2,3, 5,6,7 ...

Thus, the GFC of both is 6.

Then, the GFC of
72x ^ 3y ^ 2 and
210x ^ 2y ^ 5 is given by:


6x ^ 2y ^ 2

ANswer:


6x ^ 2y ^ 2
