Question

Find the GCF for the list. 20y^3 and 12y^2

Answer 1

1. What's the GCF of 20 and 12
2. What's the GCF of y^3 and y^2?

Answer 2

for 20 it's 1,2,5,10 for 12 i think it's 1,2,4

Answer 3

not sure for y^3 and y^2

Answer 4

You missed 4 for 20. So the GCF is 4

Answer 5

20: 1,2,4,5,10,20, 12: 1,2,3,4,6,12. GCF=4

Answer 6

For y^3 and y^2, just pick the lowest degree. y^2 is the lowest degree, so that's the greatest common factor of both. This is because you can divide both terms by y^2.

Answer 7

oh! ok gotcha. so 4 y^2 would be the answer?

Answer 8

Yup!

Answer 9
