What's the Least Common Multiple (LCM) of 11 and 15?

Answer

LCM of 11 and 15 is

165

First common multiples: 165, 330, 495, …

165 is divisible by both: 165 ÷ 11 = 15, 165 ÷ 15 = 11 — and 15 and 11 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/11 by 15 and of y/15 by 11.

11 and 15 are coprime (GCF = 1), so their LCM is simply the product: 11 × 15 = 165.

11 — prime

15 = 3 × 5

Prime	11	15	Highest power
3	—	3	3
5	—	5	5
11	11	—	11

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

LCM = 3 × 5 × 11 = 165
