<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 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 1 to 2000. 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 2000, approximately 44.72. The remaining unmarked numbers are the prime numbers. </p>
