Transposable integer

http://en.wikipedia.org/wiki/Transposable_integer


Given a positive integer k another positive integer x is said to be k-transposable if, when its leftmost digit is moved to the unit's place, the resulting integer is k*x

For example, the integer 142857 is 3-transposable since

428571 = 3 * 142857
