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

Mar 2, 2018

$\text{LCM} = 2028$

#### Explanation:

First perform prime factorisation of all three numbers.

$\implies 39 = 3 \times 13$
$\implies 52 = 4 \times 13$
=>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.

$\text{LCM} = 3 \times 4 \times 13 \times 13 = 2028$
Hope it helps!
