## How do you find a prime number greater than 100?

One can check that a number smaller than 100 is a prime just by checking that it is not divisible by 2, 3, 5, 7. This is because the next prime after 7 is 11, whose square is greater than 100 (hence the test holds if one replaces 100 by 120, note also that checking the divisibility by 9 is useless since 3 divides 9).
