2 x 3 x 3 x y x y x y
Since 3y^2 is a factor of 18y^2, it is automatically the GCF.
36xy2
6y(1) & 6y(3) The answer is 6y
72y^3
(x - 2)(9y - 2)
3(y + 4)(y + 2)
18y-8 = 10
27a3b2
9x9x9
The only common factor of those two terms is the number three, giving you: 3(x3 - 8y3)
The answer is 2 to the third power.
