What's the Least Common Multiple (LCM) of 13 and 47?

Answer

LCM of 13 and 47 is
611

First common multiples: 611; 1,222; 1,833; …

611 is divisible by both: 611 ÷ 13 = 47, 611 ÷ 47 = 13 — and 47 and 13 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/13 by 47 and of y/47 by 13.

13 and 47 are coprime (GCF = 1), so their LCM is simply the product: 13 × 47 = 611.
