You need to come up with a 4-digit number that satisfies these criteria:

A) If you divide it by 11, 13, or 7, you will end up with a remainder of 5.
B) If you divide it by 5, it will come out even.

Here's how you do it.

1) You first need to find a number that's divisible by 11, 13, and 7. Multiply these 3 numbers together.
2) The resulting number isn't divisible by 5. Multiply it by 5.
3) Add 5 to the number you got in Step #2.

This SHOULD give you the code to the safe.
