Totally 24 numbers can be made out of it. Using mathematical combination we can easily calculate it. the numbers are 1234, 1243, 1324, 1342, 1423, 1432, 2134, 2143, 2314, 2341, 2413, 1431, 3124, 3142, 3214, 3241, 3412, 3421, 4123, 4132, 4213, 4231, 4312, 4321.

64 if repetition is allowed.24 if repetition is not allowed.

That would be 4! = 4 * 3 * 2 * 1 = 24
