What's the Least Common Multiple (LCM) of 12, 16 and 24?

Answer

LCM of 12, 16 and 24 is
48

First common multiples: 48, 96, 144, …

48 is divisible by all three: 48 ÷ 12 = 4, 48 ÷ 16 = 3, 48 ÷ 24 = 2 — and 4, 3 and 2 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/12 by 4 and of y/16 by 3 and of z/24 by 2.

12 = 22 × 3

16 = 24

24 = 23 × 3
