- Divisors of 97: 1, 97
- 97 is not divisible by 2, 3, 5, or 7
Why 97 Is Prime: The Plain-English Reason
A number is prime if it has exactly two positive divisors. For 97, those are 1 and 97. If you try dividing 97 by any whole number between 2 and 96, you do not get a whole number result. For example, 97 divided by 2 is 48.5, and 97 divided by 3 is about 32.33. This confirms that no other factors exist.
