With 123 digits you can make 123 one-digit numbers.
6 if all digits are different, 27 otherwise.
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.

27 three digit numbers from the digits 3, 5, 7 including repetitions.
There are 4 options for the hundreds digit (3, 4, 5, or 6), and 4 options for the tens digit (including the possibility of repeating the hundreds digit). Similarly, there are 4 options for the units digit. Therefore, the total number of 3-digit numbers that can be formed using the digits 3, 4, 5, and 6 with repetition allowed is 4 x 4 x 4 = 64.
If you want 4-digit numbers, there are 24 of them.

There are 7,290 different 4-digit numbers that can be formed from the digits 1-9 without repetition.
7 two-digit numbers.
