Answer 2

Answer:

First, we have to know what is a composite number. A composite number is a number that has a minimum of two factors. Or we can say a whole number that can make by multiplying other whole numbers.

So, the smallest composite number is 4, and the smallest 2 digits composite number is 10.

4 is a composite number cause it has 2 factors. One is (1 *4) and, another one is (2*2)

10 is also a composite number because it also has 2 factors. One is (1 *10) and, another one is (5*2)

LCM of these two composite numbers ( 4 and 10 ) is 20.
