Not at all!"A prime number is a number that has only two divisors: itself and the number one. Examples of prime numbers are: 1, ..."

That statement is contradictory.

According to the definition given above 1 is a prime number.

1 has only two divisors (1 and itself).Number 1 does not have *two* divisors! Therefore 1 is not a prime number!

If you are going to count divisors more than once then every number has infinite divisors!
