Example:30 and 42

2 x 3 x 5 = 30

2 x 3 x 7 = 42

Combine the factors, eliminating duplicates.

2 x 3 x 5 x 7 = 210, the LCM

Multiply 210 by successive counting numbers to get more multiples.

210 x 1 = 210

210 x 2 = 420

210 x 3 = 630 and so on.

What is the least common multiple of 130 using prime factorization?

There is not a least common multiple of a single number, such as 130, because there cannot be a least common multiple without two or more numbers to compare. Common multiples are multiples that the numbers being compared have in common. The least common multiple is the smallest multiple that all the numbers being compared have in common.
