Question

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

Answer 1

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`
