Find LCM of
$12,18$ and $24$.

We have to find the L.C.M of $12,18$ and $24$.

Now,

Write the given number in their form of multiple

$12=2\times 2\times 3$

$18=2\times 3\times 3$

$24=2\times 2\times 2\times 3$

Now, on taking lowest common multiple we get,

$L.C.M=2\times 2\times 2\times 3\times 3$

$=72$

Hence, L.C.M of $12,18$ and $24$ is $72$
