What's the Least Common Multiple (LCM) of 17 and 46?

Answer

LCM of 17 and 46 is
782

First common multiples: 782; 1,564; 2,346; …

782 is divisible by both: 782 ÷ 17 = 46, 782 ÷ 46 = 17 — and 46 and 17 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/17 by 46 and of y/46 by 17.

17 and 46 are coprime (GCF = 1), so their LCM is simply the product: 17 × 46 = 782.
