<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 prime and composite numbers. 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 1351 is prime or composite.</p>

<p><strong>Step 1:</strong>All numbers are divisible by 1 and itself.</p>
26
<p><strong>Step 2:</strong>Divide 1351 by 2. It is not divisible by 2, so 2 is not a factor of 1351.</p>
26
<p><strong>Step 2:</strong>Divide 1351 by 2. It is not divisible by 2, so 2 is not a factor of 1351.</p>
27
<p><strong>Step 3:</strong>Divide 1351 by 3. It is not divisible by 3, so 3 is not a factor of 1351.</p>

<p><strong>Step 3:</strong>Divide 1351 by 3. It is not divisible by 3, so 3 is not a factor of 1351.</p>
28
<p><strong>Step 4:</strong>You can simplify checking divisors up to 1351 by finding the root value. We then need to only check divisors up to the root value.</p>

<p><strong>Divisibility by 5:</strong>The unit’s place digit is 1. Therefore, 1351 is not divisible by 5.</p>
38
<p><strong>Divisibility by 7:</strong>The last digit in 1351 is 1. To check divisibility by 7, double the last digit (1 × 2 = 2). Then, subtract it from the rest of the number (135 - 2 = 133). Since 133 is not divisible by 7, 1351 is also not divisible by 7.</p>

39
<p><strong>Divisibility by 11:</strong>In 1351, the sum of the digits in odd positions is 4, and the sum of the digits in even positions is 6. The difference is 2, making 1351 not divisible by 11 directly, although 1351 itself is divisible by 11.</p>
