Question

Find the LCM of$3,4,$and $18$.

Answer 1

Solve for LCM of given numbers

Firstly write down multiples of $3,4,$and$18$

Multiples of $3=3,6,9,12,15,18,21,24,27,30,33,36,39,42$and so on.

Multiples of $4=4,8,12,16,20,24,28,32,36,40,44$ and so on.

Multiples of $18=18,36,54,72$ and so on.

The least common multiple of $3,4,$and $18$ is $36.$

$\therefore$L.C.M.$(3,4,18)=36$

Hence, the L.C.M of $3,4,$and$18$ is$36$.
