Answer

LCM of 40 and 230 is
920

First common multiples: 920; 1,840; 2,760; …

920 is divisible by both: 920 ÷ 40 = 23, 920 ÷ 230 = 4 — and 23 and 4 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/40 by 23 and of y/230 by 4.

40 = 23 × 5

230 = 2 × 5 × 23
