<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 828 is prime or composite.</p>

<p><strong>Step 3:</strong>Divide 828 by 3. It is divisible by 3, so 3 is also a factor of 828.</p>
28
<p><strong>Step 4:</strong>You can simplify checking divisors up to 828 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 8. Therefore, 828 is not divisible by 5.</p>
38
<p><strong>Divisibility by 7:</strong>The last digit in 828 is 8. To check divisibility by 7, double the last digit (8 × 2 = 16). Then, subtract it from the rest of the number (82 - 16 = 66). Since 66 is not divisible by 7, 828 is also not divisible by 7.</p>
