Question

HELP!
what is the gcf of these monomials?

Answer 1

There's a 30 coefficient on the first and no coefficient (i.e. a 1) on the second. So the GCF of the constant part is GCF(30,1)=1.

Similarly,
`GCF(x^3, x^5)=x^3` because both have
`x^3` as a factor.

`GCF(y^4,y^3)=y^3` because both have
`y^3` as a factor.

Now that we see how the bits work it's not too hard to read these off:

`GCF(30x^3y^4, x^5y^3)=x^3y^3`
