What is the LCM of 6, 18 and 27?

What's the Least Common Multiple (LCM) of 6, 18 and 27?

Answer

LCM of 6, 18 and 27 is

54

First common multiples: 54, 108, 162, …

54 is divisible by all three: 54 ÷ 6 = 9, 54 ÷ 18 = 3, 54 ÷ 27 = 2 — and 9, 3 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 9 and of y/18 by 3 and of z/27 by 2.

6 = 2 × 3

18 = 2 × 3²

27 = 3³

Prime	6	18	27	Highest power
2	2	2	—	2
3	3	3²	3³	3³

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

LCM = 2 × 3³ = 54
