Answer 1

how far did you get with it?

Answer 2

I don't even know where to start :/

Answer 3

ok so a "greatest common factor" is the largest thing which divides all of those expressions

i would suggest breaking down each monomial into its factors, then find all the shared factors, i'll break up the first one, can you try the second one?

\[18x^2 = 2 \times 3 \times 3 \times x \times x\]

Answer 4
