What's the Least Common Multiple (LCM) of 2, 3 and 8?

Answer

LCM of 2, 3 and 8 is

First common multiples: 24, 48, 72, …

24 is divisible by all three: 24 ÷ 2 = 12, 24 ÷ 3 = 8, 24 ÷ 8 = 3 — and 12, 8 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 12 and of y/3 by 8 and of z/8 by 3.

2 — prime

3 — prime

8 = 2³

Prime	2	3	8	Highest power
2	2	—	2³	2³
3	—	3	—	3

— = power 0: the prime is not a factor of this number; the LCM takes it from the number that has it.

LCM = 2³ × 3 = 24
