For example:

4 has a factor 2 other than 1 and 4, so 4 is a composite number.

6 has factors 2 and 3 other than 1 and 6, so 6 is a composite number.

8 has factors 2 and 4 other than 1 and 8, so 8 is a composite number.

9 has a factor 3 other than 1 and 3, so 9 is a composite number.

10 has factors 2 and 5 other than 1 and 10, so 10 is a composite number.

12 has factors 2, 3, 4, and 6 other than 1 and 12, so 12 is a composite number.

14 has factors 2 and 7 other than 1 and 14, so 14 is a composite number.

15 has factors 3 and 5 other than 1 and 15, so 15 is a composite number.

etc.

 

What is the meaning of composite number?

 

Answer: The meaning of composite number is such a number which can be resolved into the factors of two or more numbers other than 1 and the number itself.

 

For example, 20 can be resolved into the factors 2 × 2 × 5 other than 1 × 20. So, 20 is a composite number. But, 23 can not be resolved into the factors other than 1 × 23, so 23 is not a composite number.

 

So, the numbers having more than two factors are composite numbers.
