Question

help please !
find the GCF of 12^a b^5 c^4 and 30a^3 b^5 c

Answer 1

please help

Answer 2

is that 12^a written correctly?

Answer 3

oh no sorry its 12a^2

Answer 4

can you figure out the GCF of 12 and 30?

Answer 5

the GCF is the highest number which will divide exactly into 12 and 30

Answer 6

so what wil the gcf be ?

Answer 7

a good way to find these is to factor each number

12 = 2*2*3
30 = 2*3*5

note that 2 and 3 match up in both factors

so gcf = 2*3 = 6

similarly the GCF of a^2 and a^3 = a^2
and of b^5 and b^5 = b^5
what about c^4 and c?
