Excuse me, but could you please clarify why the number nine is not considered a prime number? I'm curious to understand the criteria that determine whether a number is prime, and specifically how nine falls short of meeting those requirements. From my understanding, prime numbers are those that are only divisible by one and themselves, so I'm wondering what makes nine different in this regard.

The concept of prime numbers is fundamental in number theory and cryptography. A prime number is defined as a natural number greater than 1 that has no positive divisors other than 1 and itself. With this definition in mind, let's examine the number 9.
