<p>If a number has only 2 divisors, then it is considered a prime number. This means that if there are more than two divisors, it would be considered a non-prime number. In the case of 437, we can see that there are more than two divisors. </p>

<p>437/19 = 23. </p>
39
<p>Since 23 is a prime number, we can't divide it further. Therefore, we can conclude that 437 is a non-prime number and the factors are 1, 19, 23, and 437. </p>

<h3>5.Are all odd numbers considered prime numbers?</h3>
53
<p>No, all odd numbers are not prime numbers. If we take 9 as an example, we know 9 is an odd number. But 9/3 = 3, so along with 1 and 9, 3 is also a factor of 9, making it a non-prime. </p>
