It is 10000.
With repetition, the smallest is 22222 and the largest is 88888 Without repetition, the smallest is 23458 and the largest is 85432
The largest number with no repetition of digits (if that is what is meant) is 9876543210. The "smallest" number with no repetition is the negative of that if we allow negative numbers so the difference is zero. If by "smallest" we mean non-negative number, the smallest number with no repetition is 0 so the difference is the original number, 9876543210. If by "smallest" we mean smallest positive number, the smallest positive number without repeating digits is .01, so the difference is 9876543209.99. The unambiguous way to write a number smaller than 1 is to prefix it with "0." To be extremely precise, if by "no repetition" you mean to require that form and to exclude 0.01 because there are two zeros, then the smallest positive number "without repetition" is 0.1 and the difference is 9876543209.9. Everything depends on exactly what is meant by the question. It is important to avoid ambiguity in mathematics - and in everything else.
13,579 or .13579 . If I'm allowed to repeat digits, then you are 11,111 or .11111 .

The largest 4 digit number with repetition is 9999. The smallest 3 digit number without repetition is 102 9999 - 102 = 9897

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.

Just six numbers... 345, 354, 435, 453, 534 & 543
The first digit would have to be 1, the remaining digits, zero.
repetition
If leading zeros are not allowed to make the numbers, then largest = 9876, and smallest = 1023. To get the difference, just subtract: 9876 - 1023 = 8853
There are 2000 such numbers.
The largest 4 digit number with repetition is 9999. The smallest 3 digit number without repetition is 102 9999 - 102 = 9897
The number of combinations you can make with the digits 1234567890 depends on how many digits you want to use and whether repetition is allowed. If you use all 10 digits without repetition, there are 10! (10 factorial) combinations, which equals 3,628,800. If you are choosing a specific number of digits (for example, 3), the number of combinations would be calculated using permutations or combinations based on the rules you set.
