What is the LCM of 6 and 9?

What's the Least Common Multiple (LCM) of 6 and 9?

Answer

LCM of 6 and 9 is

18

First common multiples: 18, 36, 54, …

18 is divisible by both: 18 ÷ 6 = 3, 18 ÷ 9 = 2 — and 3 and 2 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/6 by 3 and of y/9 by 2.

6 = 2 × 3

9 = 3²

Prime	6	9	Highest power
2	2	—	2
3	3	3²	3²

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

LCM = 2 × 3² = 18
