What's the Least Common Multiple (LCM) of 20 and 335?

Answer

LCM of 20 and 335 is
1,340

First common multiples: 1,340; 2,680; 4,020; …

1,340 is divisible by both: 1,340 ÷ 20 = 67; 1,340 ÷ 335 = 4 — and 67 and 4 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/20 by 67 and of y/335 by 4.

20 = 22 × 5

335 = 5 × 67
