What is the Least Common Multiple (LCM) of 2 and 15? Here we will show you step-by-step how to find the Least Common Multiple of 2 and 15.

**Step 1)**First we find and list the prime factors of 2 and 15 (Prime Factorization):

Prime Factors of 2:

2

Prime Factors of 15:

3, 5

**Step 2)**Then we look at the frequency of the prime factors as they appear in each set above. List each prime factor the greatest number of times it occurs in either sets:

2, 3, 5

**Step 3)**Finally, we multiply the prime numbers from Step 2 together.

2 x 3 x 5 = 30

That's it. The Least Common Multiple (LCM) of 2 and 15 is

**30**.
