Consider using 'last'

Treating 'expected' situations with Exceptions
In the described context, it is an expected behaviour that the user might have insufficient funds. I would recommend treating similar situations with return values. Exceptions should be used for corner cases or other less frequent situations.
Make 'when' an expression
You can extract 'print' in front to make the code more concise
Factorial
Firstly, you can make the definition more compact:
fun factorial(num: Int) = if (num > 0) (2..num).fold(1, Int::times) else "Enter a positive number"
Secondly, since this is a factorial function on 'Int', one would expect and 'Int'/'Long' result rather than 'Any'. In this situation, I think it is OK to trow an IllegalArgumentException for invalid parameters.
Please write a version without a for loop
Sorting has an unnecessary overhead. Consider using 'all' or 'none'
