In order to make the smallest possible number with a set of digits, you want the least valued number in the greatest valued place. For 5 digits, you would want the least digit, 0, in the ten thousands place. You would then want the second least digit, 3, in the thousands place, and so on. For the digits 0,3,5,7,9 the smallest possible number would therefore be 03,579 or 3,579.
