What's the Least Common Multiple (LCM) of 13 and 23?

Answer

LCM of 13 and 23 is
299

First common multiples: 299, 598, 897, …

299 is divisible by both: 299 ÷ 13 = 23, 299 ÷ 23 = 13 — and 23 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 23 and of y/23 by 13.

13 and 23 are coprime (GCF = 1), so their LCM is simply the product: 13 × 23 = 299.
