Question

Largest number you can make using 1 3 5 4 7

Answer 1

75431? I think it is becuz I did it in greatest to smallest

Answer 2

I believe that the largest number that can be made using the scheme would be to simply turn it backwards, if thats not the case you can start with the 7 and add anything thats second biggest for the effect if it's going to be a 10's place number, such as 75, if your goal is bigger you can reach 75413
