The greatest possible number is 888... (repeating).
9
This is easy. Just sort the digits in descending order. That works because the further left you go, the more significant the digit. So the largest number that can be made out of the digits 5, 3, 1, 4, and 7 is 75,431.
The answer is 1. The smallest prime is 2 and the greatest prime (of however many digits) must be odd. The remainder of ANY odd number when divided by 2 must be 1.
what is the greets possible 9 digit number that uses each of the digits 1-3 times
3333
The 5 that is next to the 1.
Assuming that 000001 isn't considered as the smallest number with 6 digits on the basis that it would just be written as 1 instead: greatest whole number with 5 digits: 99,999 smallest whole number with 6 digits: 100,000 So hence the 6 digit number is the greatest. If negative numbers were involved though, then the 5 digit number would be the largest by definition. As it would still be 99,999 whereas the smallest 6 digit number would be -999,999
