16 </ul><h3>Using the Counting Divisors Method</h3>
17 <p>The method in which we count the number of divisors to categorize the numbers as prime or composite is called the counting divisors method. Based on the count of the divisors, we categorize numbers as prime or composite. If there is a total count of only 2 divisors, then the number would be prime. If the count is more than 2, then the number is composite. Let’s check whether 1393 is prime or composite.</p>

28 <p><strong>Divisibility by 5:</strong>The unit’s place digit is 3. Therefore, 1393 is not divisible by 5.</p>
27 <p><strong>Divisibility by 5:</strong>The unit’s place digit is 3. Therefore, 1393 is not divisible by 5.</p>
29 <p><strong>Divisibility by 7:</strong>To check divisibility by 7, double the last digit (3 × 2 = 6). Subtract it from the rest of the number (139 - 6 = 133). Since 133 is not divisible by 7, 1393 is not divisible by 7.</p>

37 <p><strong>Step 5:</strong>Repeat this process for other numbers like 5, 7, etc., up to the approximated<a>square root</a>. Through this process, we identify prime numbers. Although 1393 is not within the typical range of a prime number chart (up to 100), we can use similar principles to determine its primality.</p>
