<p>A composite number is a positive number that is divisible by more than two numbers. For example, 6 is divisible by 1, 2, 3, and 6, making it a composite number. Prime numbers have a few properties: Prime numbers are positive numbers always<a>greater than</a>1. 2 is the only even prime number. They have only two factors: 1 and the number itself. </p>

<p>The counting divisors method involves counting the number of divisors to categorize numbers as prime or composite. If there are only 2 divisors, then the number is prime. If the count is more than 2, then the number is composite. Let’s check whether 1125 is prime or composite.</p>

<p><strong>Step 2:</strong>Divide 1125 by 2. It is not divisible by 2, as it is an<a>odd number</a>.</p>
19
<p><strong>Step 3:</strong>Divide 1125 by 3. The<a>sum</a>of the digits (1 + 1 + 2 + 5 = 9) is divisible by 3, so 1125 is divisible by 3.</p>

<p><strong>Step 3:</strong>Divide 1125 by 3. The<a>sum</a>of the digits (1 + 1 + 2 + 5 = 9) is divisible by 3, so 1125 is divisible by 3.</p>
20
<p><strong>Step 4:</strong>Continue checking divisors up to the<a>square</a>root of 1125 (approximately 33.5). Since 1125 has more than 2 divisors, it is a composite number.</p>
