What's the Least Common Multiple (LCM) of 38 and 57?

Answer

LCM of 38 and 57 is
114

First common multiples: 114, 228, 342, …

114 is divisible by both: 114 ÷ 38 = 3, 114 ÷ 57 = 2 — and 3 and 2 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/38 by 3 and of y/57 by 2.

38 = 2 × 19

57 = 3 × 19
