142 857 is the only cyclic number.


A cyclic number is an integer in which cyclic permutations of the digits are successive multiples of the number:
142 857×1 = 142 857
142 857×2 = 285 714
142 857×3 = 428 571
142 857×4 = 571 428
142 857×5 = 714 285
142 857×6 = 857 142

142 857 is the only cyclic number (in decimal) if leading zeros are not permitted… Otherwise, there are more than one cyclic number and the next one is 0588235294117647.
