What is the LCM of 2, 3 and 12?

What's the Least Common Multiple (LCM) of 2, 3 and 12?

Answer

LCM of 2, 3 and 12 is

12

First common multiples: 12, 24, 36, …

12 is divisible by all three: 12 ÷ 2 = 6, 12 ÷ 3 = 4, 12 ÷ 12 = 1 — and 6, 4 and 1 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 6 and of y/3 by 4.

2 — prime

3 — prime

12 = 2² × 3

Prime	2	3	12	Highest power
2	2	—	2²	2²
3	—	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 = 2² × 3 = 12
