What's the Least Common Multiple (LCM) of 16 and 55?

Answer

LCM of 16 and 55 is
880

First common multiples: 880; 1,760; 2,640; …

880 is divisible by both: 880 ÷ 16 = 55, 880 ÷ 55 = 16 — and 55 and 16 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/16 by 55 and of y/55 by 16.

16 and 55 are coprime (GCF = 1), so their LCM is simply the product: 16 × 55 = 880.

16 = 24

55 = 5 × 11

— = power 0: the prime is not a factor of this number; the LCM takes it from the number that has it.

LCM = 24 × 5 × 11 = 880
