If the least common multiple of a and B is 2730, then how much is m?

If the least common multiple of a and B is 2730, then how much is m?

2730÷（2×3×5×7）＝13

If the least common multiple of a and B is 1050, then M = ()

From a = 5 × 5 × 7 × m, B = 3 × 5 × M
And M is prime
Then the least common multiple of AB is 3 × 5 × 5 × 7 × M = 1050
That is, M = 2

If the least common multiple of a and B is 2310, then n=______ What is the greatest common factor of a and B______ ．

A = 2 × 5 × 7 × n, B = 3 × 5 × n, then the least common multiple of a and B is: 2 × 3 × 5 × 7 × n = 210n, 210n = 2310, n = 2310 △ 210, so n = 11; so the greatest common factor of a and B is: 5 × 11 = 55; so the answer is: 11, 55

If the least common multiple of a and B is 770, find the value of M

If the least common multiple of a and B is 770, find the value of M
770÷2÷5÷7=m
∴m=11
