What's the Least Common Multiple (LCM) of 2, 3 and 10?

Answer

LCM of 2, 3 and 10 is
30

First common multiples: 30, 60, 90, …

30 is divisible by all three: 30 ÷ 2 = 15, 30 ÷ 3 = 10, 30 ÷ 10 = 3 — and 15, 10 and 3 have no factor but 1 common to all of them, so no smaller number is. As a common denominator: multiply the top and bottom of x/2 by 15 and of y/3 by 10 and of z/10 by 3.

2 — prime

3 — prime

10 = 2 × 5
