25, if you're talking about whole, positive numbers.
They are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89 and 97.
Many people debate whether or not 0 and 1 should also be considered prime. 0 is just weird and 1 is part of the definition of prime, so I don't think they really are prime, personally.

1 is not a prime.
prime numbers have exactly 2 factors, namely themself and 1.
1 has only 1 factor.
you can find all the prime numbers by using Erostosthenes Sieve.
Basically, cross out number one and circle number 2.Then cross out all multiples of 2.Circle 3 and crossout all multiples of 3. Next uncrossed or uncircled number is 5. Circle it and cross out all multiples of 5. Continue this process and all circled numbers will be prime.
