<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 747 is prime or composite.</p>

<p><strong>Step 3:</strong>Divide 747 by 5. It is not divisible by 5, so 5 is not a factor of 747.</p>
28
<p><strong>Step 4:</strong>You can simplify checking divisors up to 747 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 7. Therefore, 747 is not divisible by 5. </p>
38
<p><strong>Divisibility by 7</strong>: To check divisibility by 7, double the last digit (7 × 2 = 14). Then, subtract it from the rest of the number (74 - 14 = 60). Since 60 is divisible by 7, 747 is also divisible by 7. </p>
