<h3><strong>Rule 1: Divisibility Check:</strong></h3>
2
<p>Prime numbers are natural numbers that are greater than 1 and have no divisors other than 1 and the number itself. In the divisibility check rule, we check whether the prime number is divisible by 2, 3, 5, or 7. If it's divisible by these numbers then it's not a prime number.</p>

<p>The method, sieve of Eratosthenes is an ancient algorithm used to find all prime numbers up to a given limit. First, we list all the numbers from 100 to 200. Then start with the first prime number, 2. Mark all the<a>multiples</a>of 2 as non-prime. Repeat the process for the next unmarked prime number and continue until you reach the<a>square</a>root of 200, approximately 14.14. The remaining unmarked numbers are the prime numbers. </p>
