What's the Least Common Multiple (LCM) of 15 and 37?

Answer

LCM of 15 and 37 is
555

First common multiples: 555; 1,110; 1,665; …

555 is divisible by both: 555 ÷ 15 = 37, 555 ÷ 37 = 15 — and 37 and 15 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/15 by 37 and of y/37 by 15.

15 and 37 are coprime (GCF = 1), so their LCM is simply the product: 15 × 37 = 555.

15 = 3 × 5
