What is the LCM of 6, 12 and 30?

What's the Least Common Multiple (LCM) of 6, 12 and 30?

Answer

LCM of 6, 12 and 30 is

60

First common multiples: 60, 120, 180, …

60 is divisible by all three: 60 ÷ 6 = 10, 60 ÷ 12 = 5, 60 ÷ 30 = 2 — and 10, 5 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/6 by 10 and of y/12 by 5 and of z/30 by 2.

6 = 2 × 3

12 = 2² × 3

30 = 2 × 3 × 5

Prime	6	12	30	Highest power
2	2	2²	2	2²
3	3	3	3	3
5	—	—	5	5

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

LCM = 2² × 3 × 5 = 60
