What is the greatest common factor of 35x^6 and 7x^2

Answer 1

I really don't know how to do this... like i know GCF but not with variables...

Answer 2

its easy with variables

x^2 and x^6 - the greatest common factor is x^2

Answer 3

Ok, so I know that my final answer wil have x^2 in it... and since in GCF of 35 and 7 is 7 would it be 7x^2???

Answer 4

right

Answer 5

Thanks! Can I ask you a couple more just to make sure i'm correct?? :)

Answer 6

ok

Answer 7

What is the greatest common factor of 36x^3 and 8x?
Ok so i'm going to have x^3 since we only have x^3 and since the greatest common factor of 36 and 8 is 4 then would it be 4x^3???

Answer 8

Wait would it be 4x instead??? Y

Answer 9

Since x is a factor of x^3??

Answer 10

no not x^3
x^3 will not divide into x

x is the GCF of x and x^2

x^5
x^7
3x^5
