Four digits and four numbers, and finally 1 more, plus three is just enough;

There are five numbers in five positions, and two more in the end, plus three is just enough;

Six positions and six numbers, and finally three more, adding three is just enough;

So this number should be a multiple of 4, 5 and 6 at the same time, and then remove 3;

The minimum multiple of 4, 5 and 6 is 60, so 60-3=57.
