The greatest common factor of the two numbers is 12, the least common multiple is 144, and each of the two numbers is______ .

The greatest common factor of the two numbers is 12, the least common multiple is 144, and each of the two numbers is______ .

Because 144 △ 12 = 12, 12 = 1 × 12 = 3 × 4, there are two cases of these two numbers: 12 × 1 = 12, 12 × 12 = 144 or 12 × 3 = 36, 12 × 4 = 48, so the two numbers are 12144 or 36, 48 respectively
