Question

Find the LCM of the smallest composite number and smallest prime number

Answer 1

Find L.C.M. of smallest composite number and smallest prime number

We know that, a prime number is a number that has exactly two factors i.e.$1$ and itself.

So, the smallest prime number is $2$.

And, a composite number has more than two factors, i.e., apart from $1$ and itself, it can also be divided by at least one number.

So, the smallest composite number is $4$.

By using Division method, L.C.M. of $2$ and $4$ is :

L.C.M $=2\times 2=4$

Hence, Least common multiple (L.C.M) of $\mathbf{2}$ and $\mathbf{4}$ is $\mathbf{4}$.
