If a = 2x3xm, B = 3x5xm, if the greatest common divisor of a and B is 21, then what is m
The greatest common divisor of a and B is 3 × m, so the least common multiple of a and B is 2 × 3 × 7 × 5 = 210
If M and N are natural numbers and M is 8 times of N, then the least common multiple of M and N is
If M and N are natural numbers and M is 8 times of N, then the least common multiple of M and N is m
