Answer

LCM of 39 and 57 is
741

First common multiples: 741; 1,482; 2,223; …

741 is divisible by both: 741 ÷ 39 = 19, 741 ÷ 57 = 13 — and 19 and 13 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/39 by 19 and of y/57 by 13.

39 = 3 × 13

57 = 3 × 19
