What's the Least Common Multiple (LCM) of 15 and 52?

Answer

LCM of 15 and 52 is
780

First common multiples: 780; 1,560; 2,340; …

780 is divisible by both: 780 ÷ 15 = 52, 780 ÷ 52 = 15 — and 52 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 52 and of y/52 by 15.

15 and 52 are coprime (GCF = 1), so their LCM is simply the product: 15 × 52 = 780.

15 = 3 × 5

52 = 22 × 13
