What is the LCM of 9 and 24?

What's the Least Common Multiple (LCM) of 9 and 24?

Answer

LCM of 9 and 24 is

72

First common multiples: 72, 144, 216, …

72 is divisible by both: 72 ÷ 9 = 8, 72 ÷ 24 = 3 — and 8 and 3 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/9 by 8 and of y/24 by 3.

9 = 3²

24 = 2³ × 3

Prime	9	24	Highest power
2	—	2³	2³
3	3²	3	3²

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

LCM = 2³ × 3² = 72
