Some of the Properties of Prime numbers include:ġ) Every number greater than 1 can be divided by at least one prime number.Ģ) Every even positive integer greater than 2 can be expressed as the sum of two Primes.Ĥ) 2 is the only even number which is Prime.ĥ) Two primes are always co prime to each other. Therefore, the Number of Prime between 1 to 100 is 25. Here, we can see that the total count of prime numbers is 25. So, we will list all the numbers which have only 2 factors : 1 and the number itself. We know that the factors of a Prime number are 1 and itself. Prime numbers are defined as a number having only two positive integers as their factors.
We will list all the prime numbers between 1 to 100 and count them to find the required answer. Here, we will use the concept of Prime numbers to answer this question.
