Additional comment
This is done by putting the largest digit in the number place with the greatest place value, repeating until you run out of digits. Here, the smallest digit is odd, so the number ends up being odd.
If the smallest digit were even, you'd have reserve the smallest odd digit to put in the ones place. For example, if your digits were 2, 4, 5, 6, then the largest odd number you could build would be 6425.
