If you're limited to only 5 digits that can't be repeated, then there are 120 ways they can be arranged.

-- If the same digit may be repeated, then 64 can be made. -- If the same digit may not be repeated, then 24 can be made.
1,956 different numbers can be made from 6 digits. You can calculate this by using the permutation function in a summation function, like this: Σ6k=1 6Pk = 6P1+6P2+...+6P5+6P6 What this does is calculate how many 1 digit numbers you can make from 6 digits, then how many 2 digit numbers can be made from 6 digits and adds the amounts together, then calculates how many 3 digit numbers can be made and adds that on as well etc.
874321 is the largest number made from all these digits.

If you can repeat a digit, there are 27. If you can't repeat a digit, there are only 6.
There are 4 possible numbers if the digits are not repeated; 18 if they are. Those are 3-digit numbers, assuming that zero would not be a leading digit. If zero is allowed for a leading digit, then you can have 6 for the non repeated, and 27 if repetition.
-- If the same digit may be repeated, then 64 can be made. -- If the same digit may not be repeated, then 24 can be made.

24 three digit numbers if repetition of digits is not allowed. 4P3 = 24.If repetition of digits is allowed then we have:For 3 repetitions, 4 three digit numbers.For 2 repetitions, 36 three digit numbers.So we have a total of 64 three digit numbers if repetition of digits is allowed.
874321 is the largest number made from all these digits.

Well, honey, if you're using 3, 6, and 9 to make a 3-digit number with repetition allowed, you've got 3 choices for each digit. So that's 3 choices for the hundreds place, 3 choices for the tens place, and 3 choices for the units place. Multiply those together and you get 3 x 3 x 3, which equals 27 possible 3-digit numbers. Math made sassy!
Six: 234, 243, 324, 342, 423, and 432.
