Question

Find the greatest common factor of 15x^2 y^3 and -18x^3 yz

Answer 1

It should be 3x^2y
I'm using 3 from numbers because 3 is a GCF of 18 and 15
Then I'm getting X^2 because it's the GCF of X^2 and X^3
Then I'm taking y because it's the GCF of y^3 and y
And finally we got no z on the left side so we get 3x^2y

Answer 2

The answer would be : 3 x^2 y^1
