Puzzle analysis - Fallout 3 Jigg's Loot

In a players Fallout 3 adventures, they might run across the corpse of a man named "Prime". On this corpse the player can loot a note from Prime (to an unknown NPC) stating how he has stashed some special loot in the museum of technology and that they can find it by following the breadcrumbs he left behind.

In the Museum of Technology, there are terminals that the player can acess with a special number ranging from 1-3. Clicking on the numbers in the terminal will give the player an option of 5 numbers to choose from with only one of them being the correct one. There is no room for error because choosing the wrong number will lock the player out of the terminals permanently so that they will never be able to access Prime's loot safe.

There is really no "breadcrumbs" for the player to find and instead they have to think a little creatively to realize that Prime's name is the only hint they need to solve the puzzle. Out of all the numerical options available on each terminal, one of them will be an actual prime number. This is always the correct number and some of them are large, so it might require a little math from the player but choosing all of them will unlock a special safe at the end of the museum of technology. 

In this safe is a decent amount of money and one of the best guns in the game.

types of puzzles:

-Information Puzzle - for Fallout 3, this is a really cryptic puzzle but anyone with a little math knowledge should be able to figure it out eventually.

-Sequence Puzzle - The player needs to do the terminals in order, from #1-3

Figuring out this puzzle will make the player feel really smart since there are really no other clues connecting Prime to the numbers in the terminals. Prime also throws you off saying that there are "breadcrumbs", implying there are clues in the Museum of Technology, which there are none. The reward is also well worth the time put into the puzzle.
