What's the Least Common Multiple (LCM) of 7 and 100?

Answer

LCM of 7 and 100 is
700

First common multiples: 700; 1,400; 2,100; …

700 is divisible by both: 700 ÷ 7 = 100, 700 ÷ 100 = 7 — and 100 and 7 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/7 by 100 and of y/100 by 7.

7 and 100 are coprime (GCF = 1), so their LCM is simply the product: 7 × 100 = 700.
