What's the Least Common Multiple (LCM) of 51 and 58?

Answer

LCM of 51 and 58 is
2,958

First common multiples: 2,958; 5,916; 8,874; …

2,958 is divisible by both: 2,958 ÷ 51 = 58; 2,958 ÷ 58 = 51 — and 58 and 51 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/51 by 58 and of y/58 by 51.

51 and 58 are coprime (GCF = 1), so their LCM is simply the product: 51 × 58 = 2,958.

51 = 3 × 17

58 = 2 × 29
