What's the Least Common Multiple (LCM) of 2, 6 and 10?

Answer

LCM of 2, 6 and 10 is

First common multiples: 30, 60, 90, …

30 is divisible by all three: 30 ÷ 2 = 15, 30 ÷ 6 = 5, 30 ÷ 10 = 3 — and 15, 5 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 15 and of y/6 by 5 and of z/10 by 3.

2 — prime

6 = 2 × 3

10 = 2 × 5

Prime	2	6	10	Highest power
2	2	2	2	2
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 = 2 × 3 × 5 = 30
