What's the Least Common Multiple (LCM) of 55 and 121?

Answer

LCM of 55 and 121 is
605

First common multiples: 605; 1,210; 1,815; …

605 is divisible by both: 605 ÷ 55 = 11, 605 ÷ 121 = 5 — and 11 and 5 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/55 by 11 and of y/121 by 5.

55 = 5 × 11

121 = 112
