Question

L.C.M of the smallest prime number and the smallest composite number is ………….. .

Answer 1

Since as we know that the smallest prime number is $2$ and smallest composite number is $4.$

Multiples of $2=2,4,6,8,10,.............$

Multiples of $4=4,8,10,12,.......$

L.C.M $(2,4)=2$

Hence, least common multiple of the smallest prime number and the smallest composite number is $2.$
