What's the Least Common Multiple (LCM) of 10 and 385?

Answer

LCM of 10 and 385 is
770

First common multiples: 770; 1,540; 2,310; …

770 is divisible by both: 770 ÷ 10 = 77, 770 ÷ 385 = 2 — and 77 and 2 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/10 by 77 and of y/385 by 2.

10 = 2 × 5

385 = 5 × 7 × 11
