Best ResponseYou've already chosen the best response.2well, can you list the factors of 8?

Best ResponseYou've already chosen the best response.2uh, not quite... the factors of 8 are: 1,2,4, and 8 and the factors of 36 are: 1,2,4,9,12, 18, and 36 so our GCF is 4, since this is the highest number they both have in common with me so far?

Best ResponseYou've already chosen the best response.0i Div 8 by 36 and i got 28. How did you get 4

Best ResponseYou've already chosen the best response.2I don't mean "divide 8 by 36" , I meant to find the biggest number that goes into 8 and 36

Best ResponseYou've already chosen the best response.2just 4, not 4x, we'll get to the x in a minute now, we factor out 4 giving us: 8x5 − 36x2 = 4(2x^59x^2)

Best ResponseYou've already chosen the best response.2now, the GCF of x^5 and x^2 is x^2, so we factor that out, giving us: 4x^2(2x^39) which is our answer
