Question

Consider the monomials 15x^2y^2 and 6x^3y.
a. Factor the monomials.
b. What factors of these monomials are common factors?
c. Find the greatest common factor of 15x^2y^2 and 6x^3y.

(UPDATED VER.)

Answer 1

15x^2y^2 = 3*5*x*x*y*y
6x^3y = 2*3*x*x*x*y

I see a 3 common to both of them
a pair of x's common to both of them
a single y common to both of them, so .......

Answer 2

Thank you so much!
