What's the Least Common Multiple (LCM) of 50 and 390?

Answer

LCM of 50 and 390 is
1,950

First common multiples: 1,950; 3,900; 5,850; …

1,950 is divisible by both: 1,950 ÷ 50 = 39; 1,950 ÷ 390 = 5 — and 39 and 5 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/50 by 39 and of y/390 by 5.

50 = 2 × 52

390 = 2 × 3 × 5 × 13
