How to find the least common multiple of two numbers by decomposing prime factor

How to find the least common multiple of two numbers by decomposing prime factor

For example, 16, 18,
16=2*2*2*2
18=3*3*2*2
The least common multiple of 16 and 18 is: 2 * 2 * 2 * 2 * 3 * 3 = 18

The least common multiple 30 and 12 30 = 2 * 3 * 5, 12 = 2 * 3 * 2 of each group under the ball by decomposing the prime factor
The common prime factors of 30 and 12 are () and (), the unique prime factors of 30 are (), the unique prime factors of 12 are (), and the least common multiple of 30 and 12 is ()

The prime factors of 30 and 12 are (2,) and (3),
The unique quality factors of 30 are (5)
The unique quality factors of 12 are (2),
The least common multiple of 30 and 12 is (60)

A = 2x2x3, B = 2x3x5, the greatest common factor degree of a and B is () and the least common multiple is ()

A = 12 b = 30 the greatest common factor is 6 and the least common multiple is 60
