142857 is a cyclic number - its digits always appear in the same order but will rotate around when multiplied by any number from 1 to 6:
142857 x 1 = 142857
142857 x 2 = 285714
142857 x 3 = 428571
142857 x 4 = 571428
142857 x 5 = 714285
142857 x 6 = 857142 Pretty cool, huh?
Now multiply 142857 by 7 and look what comes out
