142857 is a curious number:

1 * 142857 = 142857

2 * 142857 = 285714

3 * 142857 = 428571

4 * 142857 = 571428

5 * 142857 = 714285

6 * 142857 = 857142

Note that the numbers are the same and in the same order circularly

7 * 142857 however = 999999.

Explanation, anyone? Or is it just a coincidence?
