What's the Least Common Multiple (LCM) of 3, 6 and 8?

Answer

LCM of 3, 6 and 8 is
24

First common multiples: 24, 48, 72, …

24 is divisible by all three: 24 ÷ 3 = 8, 24 ÷ 6 = 4, 24 ÷ 8 = 3 — and 8, 4 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/3 by 8 and of y/6 by 4 and of z/8 by 3.
