What's the Least Common Multiple (LCM) of 5, 6 and 10?

Answer

LCM of 5, 6 and 10 is
30

First common multiples: 30, 60, 90, …

30 is divisible by all three: 30 ÷ 5 = 6, 30 ÷ 6 = 5, 30 ÷ 10 = 3 — and 6, 5 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/5 by 6 and of y/6 by 5 and of z/10 by 3.

5 — prime

6 = 2 × 3

10 = 2 × 5
