If the digits are only used once, each, the largest possible number would be 97,531
The smallest number is 5,789. The largest is 98,750. The difference is 92,961.
86432
The largest integer that can be formed by using the digits only once each and simply arranging them in some order is 8740. Otherwise, using exponents, much larger numbers are possible.
