What's the Least Common Multiple (LCM) of 5 and 19?

Answer

LCM of 5 and 19 is
95

First common multiples: 95, 190, 285, …

95 is divisible by both: 95 ÷ 5 = 19, 95 ÷ 19 = 5 — and 19 and 5 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/5 by 19 and of y/19 by 5.

5 and 19 are coprime (GCF = 1), so their LCM is simply the product: 5 × 19 = 95.
