What's the Least Common Multiple (LCM) of 14 and 57?

Answer

LCM of 14 and 57 is
798

First common multiples: 798; 1,596; 2,394; …

798 is divisible by both: 798 ÷ 14 = 57, 798 ÷ 57 = 14 — and 57 and 14 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/14 by 57 and of y/57 by 14.

14 and 57 are coprime (GCF = 1), so their LCM is simply the product: 14 × 57 = 798.

14 = 2 × 7

57 = 3 × 19
