This calculator finds the least common multiple (LCM) of a set of integers. It can be used to find it for two or more numbers.

Here's an example. To find the least common multiple of 4 and 6 we could list the multiples of each of them:
Another common technique is to use the greatest common divisor \( \def\myfunc{\text{lcm}} \) \begin{equation} \myfunc(a, b) = \frac{|a \times b|}{\gcd(a, b)}. \end{equation} To apply it to three numbers \(a, b\) and \(c\) you can simply use \(\myfunc(a, \myfunc(b, c))\).
