Question

L.C.M. of smallest composite number and the smallest two-digit number is ………… .

Answer 1

Since as we know that smallest composite number is $4=4,8,12,16,20,.........$ and the smallest two-digit number is $10.$

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

Multiples of $10=10,20,30,40,.........$

Hence, least common multiples of smallest composite number and the smallest two-digit number is $20.$
