Example of Prime number
The perfect example of a prime number would be 7
The number 7 has only 2 different factors which are 1 and 7
The number 17 has only 3 different factors which are 1 and 17
Note: If a number has two digits it does not mean that it is a composite number. If the two digit number has only 2 different factors it is still considered to be a prime number.
