Find the LCM of $32$ and $640$.

We need to find the Least Common Multiple ($\text{LCM}$) of $32$ and $640$.Let's check if the larger number ($640$) is perfectly divisible by the smaller number ($32$):
$$\frac{640}{32}=20$$
Since $640$ is a multiple of $32$, the $\text{LCM}$ of $32$ and $640$ is the larger number itself, which is $640$.
