To form a four-digit number using the digits 1, 2, 3, 4, 5, and 6 without repeating any digits, you can choose the first digit in 6 ways, the second digit in 5 ways, the third digit in 4 ways, and the fourth digit in 3 ways. Therefore, the total number of four-digit combinations is calculated as (6 \times 5 \times 4 \times 3 = 360). Thus, 360 different four-digit numbers can be formed.

5040 different 4 digit numbers can be formed with the digits 123456789. This is assuming that no digits are repeated with each combination.
There are 25 such numbers.
To form a four-digit number without repeating any digits from 56789, we need to choose 4 different digits out of the 5 available. This can be done in 5 choose 4 ways, which is equal to 5! / (4! * (5-4)!) = 5 ways. Therefore, there are 5 four-digit numbers that can be formed out of 56789 without repeating any digits.
id say, 0123456789. but depends how many digits you can have
