What are Prime and Composite Numbers?
Prime Numbers:
Numbers that have only two factors (are perfectly divisible by only two numbers) i.e. one and itself.
For example, 5 is a prime number as 5 has only two factors, 1 and 5. 2, 3, 5, 7, 11, 13, 17....and so on.
Composite numbers are those numbers that are NOT prime numbers. These numbers have three or more factors which include 1 as well.
