What is Meant by the Prime Number?

In mathematics, the numbers are used to express the quantitative measure. The numbers can be classified into different types, namely real numbers, whole numbers, natural numbers, complex numbers, and so on. The prime numbers are considered as the whole numbers or the positive integers which have exactly two factors, i.e. 1 and the number itself. If the numbers have more factors, then the number is not a prime number. For example, 5 is a prime number. Because 5 is divided by the number 1 and 5 only.
