In order to find the least common multiple (LCM) of these three numbers, first let's factorate them:

$\begin{gathered} 30\to2\cdot3\cdot5 \\ 20\to2\cdot2\cdot5 \\ 50\to2\cdot5\cdot5 \end{gathered}$

The LCM will be the product of each factor in the maximum amount of time they appear.

So we have:

$\text{LCM}=2\cdot2\cdot3\cdot5\cdot5=300$

So the LCM is 300.
