Question

Find the Lowest Common Multiple (LCM) of 105, 28, and 63.I

Answer 1

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

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:

$\begin{gathered} 105=3\times5\times7 \\ 28=2^2\times7 \\ 63=3^2\times7 \end{gathered}$

The LCM is now:

$7\times3^2\times5\times2^2=1260$
