Question

find the lcm of smallest two digit composite number and smallest composite number​

Answer 1

Composite Number :- Any number which has more than 2 factors is a composite number.

So smallest 2 digit composite number :- 10 (factors 1,2,5 & 10)

And smallest composite number is 4 (factors 1,2 & 4)

So the LCM of 4 and 10 is 20
