What is the LCM of 22 and 28?

What's the Least Common Multiple (LCM) of 22 and 28?

Answer

LCM of 22 and 28 is

308

First common multiples: 308, 616, 924, …

308 is divisible by both: 308 ÷ 22 = 14, 308 ÷ 28 = 11 — and 14 and 11 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/22 by 14 and of y/28 by 11.

22 = 2 × 11

28 = 2² × 7

Prime	22	28	Highest power
2	2	2²	2²
7	—	7	7
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 = 2² × 7 × 11 = 308
