Why 2 is not a prime number?
I'm curious to understand why the number 2 is not considered a prime number. Isn't a prime number defined as a natural number greater than 1 that has no positive divisors other than 1 and itself? Since 2 is the only even prime number and it only has two factors, 1 and 2 itself, shouldn't it fulfill the criteria of being a prime number? Can you explain the reasoning behind why 2 is excluded from the definition of prime numbers, or if my understanding of prime numbers is flawed?
