<p>Rule 1: Divisibility Check: 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, check whether the number is divisible by 2, 3, 5, and 7. If it's divisible by these numbers, it's not a prime number.</p>
