The greatest 9-digit number using three different digits is 999888777, formed by using the digits 9, 8, and 7 in descending order. The smallest 9-digit number using three different digits is 100000000, created with the digits 1, 0, and 0. This arrangement ensures that the number starts with 1, followed by the zeros to maintain the smallest value.
The greatest 5-digit number using 3 different digits is 99987. This number is formed by using the digit '9' three times, along with '8' and '7' to maximize the overall value while adhering to the condition of using only three different digits. Other combinations, like 99876 or 99875, do not yield a higher number while still using only three distinct digits.
Assuming each digit only once: 65432 (and no further mathematical operations).
