What's the Least Common Multiple (LCM) of 50 and 220?

Answer

LCM of 50 and 220 is
1,100

First common multiples: 1,100; 2,200; 3,300; …

1,100 is divisible by both: 1,100 ÷ 50 = 22; 1,100 ÷ 220 = 5 — and 22 and 5 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/50 by 22 and of y/220 by 5.

50 = 2 × 52

220 = 22 × 5 × 11
