Answer:
\text{LCM}(105,28,63)=1260

Step-by-step explanation:

Given 105, 28 and 63, we want to find the Lowest Common Multiple (LCM)

We have the numbers written as product of prime factors as follows:


\begin{gathered} 105=3*5*7 \\ 28=2^2*7 \\ 63=3^2*7 \end{gathered}

The LCM is now:


7*3^2*5*2^2=1260
