Including leading zeroes, the answer is 720. If you don't include leading zeroes, then 600.
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.

To make whole numbers. The numbers 1,2,4,17,34,68. So 6 numbers.
With 4 different numbers, 24.

Using 1, 2, and 3, you can make 27 whole numbers.
With 123 digits you can make 123 one-digit numbers.
