The $\"biggest\"$ number that can be formed with just those four digits once each, is $\"8641\"$ - however - $\"no\"$ $\"+number\"$ made from those digits can be $\"divided\"$ by $\"9\"$ because in order for a number to be exactly divisible by nine - $\"the\"$ $\"+sum\"$ of the digits $\"must\"$ also divide exactly by nine. The sum of the digits $\"6%2B4%2B8%2B1=+19\"$ .\r
