1. \sqrt{97} \approx 9

   Only primes up to √97 need testing: any factor above it pairs with one below.

2. 97 \bmod 2 = 1

   2 does not divide 97.

3. 97 \bmod 3 = 1

   3 does not divide 97.

4. 97 \bmod 5 = 2

   5 does not divide 97.

5. 97 \bmod 7 = 6

   7 does not divide 97.

6. \text{97 is prime}

   No prime up to the square root divides it, so it has no factors other than 1 and itself.
