1. Find the GCF of the following:

Question

a) xy, y2x, x2y

b) x2, x3, x3

c) y2(2y - 1), 3(2y - 1)

how do i do this can someone please explain'

Answer 1

which factor is found in all of your terms?
e.g. xy, y2x, x2y
I see xy in the first, the 2nd and the 3rd term, so xy is the HCF

You appear to have a typo in the 2nd question
x^3 appears twice, unless that was the intention.

Answer 2

Y2x
