The smallest number that someone can get using the 91764 digits is 14679. The secret is to arrange the digits from the least number to their greatest number.
Standard Form
9,999,876 is the greatest seven-digit number using four different digits.
75431
75431
9,876,543,210
I guess the expected answer is 97210. Using factorials and exponents very much greater number can be obtained. For example, 97210 is a number with 6880 digits. And that is without using factorials.

There are only 6 digits and if they can only be used once then there is no way to string them together to make a number which is 7 (or more) digits in length.
You get the largest number if you sort the digits, from largest to smallest.
