<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 608 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 608 by 2. It is divisible by 2, so 2 is a factor of 608.</p>
26
<p><strong>Step 2:</strong>Divide 608 by 2. It is divisible by 2, so 2 is a factor of 608.</p>
27
<p><strong>Step 3:</strong>Divide 608 by 3. It is not divisible by 3, so 3 is not a factor of 608.</p>
27
<p><strong>Step 3:</strong>Divide 608 by 3. It is not divisible by 3, so 3 is not a factor of 608.</p>
28
<p><strong>Step 4:</strong>You can simplify checking divisors up to 608 by finding the root value. We then need to only check divisors up to the root value.</p>

36
<p><strong>Divisibility by 3:</strong>The<a>sum</a>of the digits in the number 608 is 14. Since 14 is not divisible by 3, 608 is also not divisible by 3.</p>

36
<p><strong>Divisibility by 5:</strong>The unit’s place digit is 8. Therefore, 608 is not divisible by 5.</p>
38
<p><strong>Divisibility by 7:</strong>The last digit in 608 is 8. To check divisibility by 7, double the last digit (8 × 2 = 16). Then, subtract it from the rest of the number (60 - 16 = 44). Since 44 is not divisible by 7, 608 is also not divisible by 7.</p>

39
<p><strong>Divisibility by 11:</strong>In 608, the sum of the digits in odd positions is 6 + 8 = 14, and the sum of the digits in even positions is 0. This would<a>mean</a>that the difference, 14, is not divisible by 11. Therefore, 608 is not divisible by 11.</p>
