What's the Least Common Multiple (LCM) of 11 and 42?

Answer

LCM of 11 and 42 is

462

First common multiples: 462; 924; 1,386; …

462 is divisible by both: 462 ÷ 11 = 42, 462 ÷ 42 = 11 — and 42 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 42 and of y/42 by 11.

11 and 42 are coprime (GCF = 1), so their LCM is simply the product: 11 × 42 = 462.

11 — prime

42 = 2 × 3 × 7

Prime	11	42	Highest power
2	—	2	2
3	—	3	3
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 = 2 × 3 × 7 × 11 = 462
