What's the Least Common Multiple (LCM) of 11 and 39?

Answer

LCM of 11 and 39 is
429

First common multiples: 429; 858; 1,287; …

429 is divisible by both: 429 ÷ 11 = 39, 429 ÷ 39 = 11 — and 39 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 39 and of y/39 by 11.

11 and 39 are coprime (GCF = 1), so their LCM is simply the product: 11 × 39 = 429.
