Question

How do you find the LCM of the 39, 52, 169?

Answer 1

`"LCM" = 2028`

Explanation:

First perform prime factorisation of all three numbers.

`=>39=3xx13`
`=>52=4xx13`
`=>169=13×13`

As we can see `13` is common in all. So it is H.C.F.

Multiply other three numbers which are not common and 13.

`"LCM" = 3xx4xx13xx13=2028`
