Hey there!
What I would do to solve this problem is list out all four of the numbers, then place the other three numbers behind it, like so:
71
73
79
17
13
19
37
31
39
97
91
93
These are all of your possible combinations without any repeats. There's a total of 12 possible combos.
Hope this helped you out! :-)
