However, there are multiple combinations that can have a sum of 6: 1&5, 2&4, 3&3, 4&2, 5&1, and one combo that can yield 12: 6&6; 6 possible combinations / 36 total combos = 1/6 = 0. Hence 1683 is the least number which when divided by 5, 6, 7 and 8 leaves a remainder 3, but when divided by 9 leaves no remainder.
