What makes a number prime?
A number is prime if it has only two distinct positive divisors: 1 and itself.
To understand whether 72 is prime, it's essential to grasp the concept of primality. A prime number is a positive integer greater than 1 that has no positive divisors other than 1 and itself. In other words, the only numbers you can divide a prime number by are 1 and the number itself. For example, 5 is prime because the only numbers you can divide it by are 1 and 5. On the other hand, 6 is not prime because it can be divided by 1, 2, 3, and 6.
