Fallout 3 Hints
What's the answer to the third prime puzzle?
1 of 5: This one is a lot tougher than the last one, since all of the numbers are odd.
2 of 5: 99 can be easily eliminated, since it's clearly divisible by 3.
3 of 5: 105 can be divided by 5, leaving only 111 and 113 as possibilities.
4 of 5: Both of those numbers look totally prime, but it turns out that 111 can be divided by 3.
