Answer

LCM of 39 and 48 is
624

First common multiples: 624; 1,248; 1,872; …

624 is divisible by both: 624 ÷ 39 = 16, 624 ÷ 48 = 13 — and 16 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 16 and of y/48 by 13.

39 = 3 × 13

48 = 24 × 3
