What's the Least Common Multiple (LCM) of 60 and 66?

Answer

LCM of 60 and 66 is
660

First common multiples: 660; 1,320; 1,980; …

660 is divisible by both: 660 ÷ 60 = 11, 660 ÷ 66 = 10 — and 11 and 10 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/60 by 11 and of y/66 by 10.

60 = 22 × 3 × 5

66 = 2 × 3 × 11
