176 views

A number is not prime if it can be divided evenly by any other whole number besides 1 and itself. This means it must have more than two factors. For example, the number 6 is not prime because it can be divided by 1, 2, 3, and 6. Essentially, if you can find a divisor other than 1 and the number itself that produces a whole number quotient, the number is not prime. This characteristic makes recognizing prime numbers straightforward in most cases.
