<p>The counting divisors method involves identifying the number of divisors a number has to determine whether it is prime or composite. Based on the count of the divisors: If there are only 2 divisors, the number is prime. If there are more than 2 divisors, the number is composite. Let’s check whether 622 is prime or composite.</p>
