What's the Least Common Multiple (LCM) of 23 and 39?

Answer

LCM of 23 and 39 is
897

First common multiples: 897; 1,794; 2,691; …

897 is divisible by both: 897 ÷ 23 = 39, 897 ÷ 39 = 23 — and 39 and 23 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/23 by 39 and of y/39 by 23.

23 and 39 are coprime (GCF = 1), so their LCM is simply the product: 23 × 39 = 897.
