Prime and Composite Numbers

Having some fun learning Prime and Composite numbers!

Prime Numbers

Prime numbers are those which have only two factors. 1 and the number itself.

Eg: 2, 3, 5, 7, 11, 13, 17 and 19 are the prime numbers between 1 and 20.

Composite Numbers 

Numbers which have more than two factors are called composite numbers.

Eg: 4, 6, 8, 9, 10, 12, 14, 15, 16, 18 and 20 are the composite numbers between 1 and 20.
