what is the greatest common factor for each set of #s-?

Question

24=2^3X3
36=2^2X3^2
48=2^4X3
SORRY I ASKED AGAIN I DONT GET THIS ONE SORRY

Answer 1

24 = 12x2
36 = 12x3
48 = 12x2x2,
so gcf = 12

Answer 2

Given a set of integers, write all of them as a product of prime powers.Then rewrite them using THE SAME PRIMES for all (possibly with exponent 0). The gcf is the product of those same primes, each raised to the lowest power for that prime in the list. Example: to find the gcf of180, 54, and 8100, find

180 = (2^2)*(3^2)*(5^1)
54 = (2^1)*(3^3)*(5^0)
8100 = (2^2)*(3^4)*(5^2).

Now the gcf is (2^1)*(3^2)*(5^0) = 18.
