Question

find the gcf of 69x^4y^2,84xy^2,108x^2y^2

Answer 1

Well, the y^2 bit is easy, it's in everything so y^2 is part of it.
For x, we have a single x in the middle one so we can't go higher than that, so x.
U can do the last bit, what's the highest number you can find that divides into 69,84 and 108 (factorize them to see).
