The least common multiple: 24 and 28, 20 and 45, 15.18 and 30, 6.15 and 27, 8.10 and 20, 6.9.15 and 20 Is the least common multiple, no greatest common divisor, wrong number, sorry

168,180,90,270,40,180

What are the greatest common factors of 27 and 60, 32 and 16, what are the least common multiples of 30 and 24, 24 and 18

27 and 60 are three
32 and 16 are 16
30 and 24 are 120
24 and 18 are 72

The greatest common divisor of 36 and 54 is______ The least common multiple is______ ．

Because 36 = 2 × 2 × 3 × 3, 54 = 2 × 3 × 3, the greatest common divisor of 36 and 54 is 2 × 3 × 3 = 18, and the least common multiple is 2 × 2 × 3 × 3 × 3 = 108
