What's the Least Common Multiple (LCM) of 100 and 255?

Answer

LCM of 100 and 255 is
5,100

First common multiples: 5,100; 10,200; 15,300; …

5,100 is divisible by both: 5,100 ÷ 100 = 51; 5,100 ÷ 255 = 20 — and 51 and 20 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/100 by 51 and of y/255 by 20.

100 = 22 × 52

255 = 3 × 5 × 17
