<p>Prime numbers follow a few properties like: 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. Any two distinct prime numbers are<a>co-prime numbers</a>because they have only one common factor, which is 1.</p>

<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 1398 is prime or composite.</p>

<p><strong>Divisibility by 2:</strong>The number is even, so 1398 is divisible by 2.</p>
25
<p><strong>Divisibility by 2:</strong>The number is even, so 1398 is divisible by 2.</p>
27
<p><strong>Divisibility by 3:</strong>The sum of the digits in 1398 is 21, which is divisible by 3, so 1398 is divisible by 3.</p>
26
<p><strong>Divisibility by 3:</strong>The sum of the digits in 1398 is 21, which is divisible by 3, so 1398 is divisible by 3.</p>
28
<p><strong>Divisibility by 5:</strong>The last digit is not 0 or 5, so 1398 is not divisible by 5.</p>
27
<p><strong>Divisibility by 5:</strong>The last digit is not 0 or 5, so 1398 is not divisible by 5.</p>
29
<p><strong>Divisibility by 7:</strong>To check divisibility, double the last digit (8 × 2 = 16) and subtract it from the rest of the number (139 - 16 = 123). Since 123 is divisible by 7, 1398 is divisible by 7.</p>
28
<p><strong>Divisibility by 7:</strong>To check divisibility, double the last digit (8 × 2 = 16) and subtract it from the rest of the number (139 - 16 = 123). Since 123 is divisible by 7, 1398 is divisible by 7.</p>
30
<p><strong>Divisibility by 11:</strong>The difference between the sum of digits in odd positions (1 + 9 = 10) and even positions (3 + 8 = 11) is 1, not divisible by 11, so 1398 is not divisible by 11. Since 1398 is divisible by 2, 3, and 7, it has more than two factors. Therefore, it is a composite number.</p>
29
<p><strong>Divisibility by 11:</strong>The difference between the sum of digits in odd positions (1 + 9 = 10) and even positions (3 + 8 = 11) is 1, not divisible by 11, so 1398 is not divisible by 11. Since 1398 is divisible by 2, 3, and 7, it has more than two factors. Therefore, it is a composite number.</p>
