We know that the factors of a Prime number are 1 and itself.

So, we will list all the numbers which have only 2 factors : 1 and the number itself.

The Prime numbers between the numbers 1 to 100 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, 97.

Here, we can see that the total count of prime numbers is 25.
