In simple, prime numbers are those numbers which is exactly divide itself. Here the number "1" is excluded, since it is the common factor of all the numbers.

For example, 2 is exactly divisible by 2 only [excluding 1], so 2 is a prime number

Similarly, 3 is exactly divisible by 3 only [excluding 1], so, 3 is a prime number

and so on.

Hope you have got the concept of prime numbers.
