Question

Factor out the greatest common factor from the expression
16x^3y^2z^3-2x^2yz^3+14^3z^4

Answer 1

look at each term and see that variable they have in common....
unless you are missing somthing after 14 on the lest term then it's z and that is the lowest power of z?
then look at the coeffs. look like it's 2

Answer 2

factor out 2z^3(8x^3*y^2-2x^2*2y=14^3*z)
