How do you list the prime numbers between 90 and 100?

I list them like this: 97

First, we can ignore any multiple of 2, namely 92, 94, 96 ,98

91 is not prime, (divisible by 7 and 13) 93 is not prime (divisible by 3 and 31) 95 is not prime (divisible by 5 and 19) 97 is prime 99 is not prime (divisible by 3 and 33)
