Why is 67 not a prime number?
Could you explain to me why 67 is not considered a prime number? As I understand, a prime number is a whole number greater than 1 that has no divisors other than 1 and itself. So, when I look at 67, it seems to me that it only has 1 and 67 as its divisors, making it a prime number. Could you clarify why this is not the case?
