What's the Least Common Multiple (LCM) of 23 and 100?

Answer

LCM of 23 and 100 is
2,300

First common multiples: 2,300; 4,600; 6,900; …

2,300 is divisible by both: 2,300 ÷ 23 = 100; 2,300 ÷ 100 = 23 — and 100 and 23 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/23 by 100 and of y/100 by 23.

23 and 100 are coprime (GCF = 1), so their LCM is simply the product: 23 × 100 = 2,300.
