Best ResponseYou've already chosen the best response.0\[72 = 2 \times 2 \times 2 \times 3 \times3\]\[78 = 2 \times 3 \times 13\]what factors do 72 and 78 have in common?

Best ResponseYou've already chosen the best response.072 can divide by 1, 2, 3, 4, 6, 8, 12, 18, 24, 36, 72 78 can divide by 1, 2, 3, 6, 13, 26, 39, 78. so 6 is the greatest common factors
