What is the sum of all the numbers formed by taking each of the digits 2,3,5,6 and 8 once?

If I answered the right question, for all of the 5-digit numbers you can make, each digit appears 24 times in each column, so you can write:
24*(22222+33333+55555+66666+88888)=6399936
Edit: Oh, I thought it was the sum of the numbers made by the combinations, not the sum of their digits.
The largest possible number that can be formed using these digits is 86532.
The smallest possible number that can be formed using these digits is 23568.
A total of 120 different numbers can be formed using these digits.
The sum of all the numbers that can be formed using these digits is 240,000.
Yes, the digits should be arranged in descending order from left to right to form the largest possible number. In this case, it would be 8, 6, 5, 3, 2.
