## Description
|
||
<section id='description'>
|
||
Consider the number 142857. We can right-rotate this number by moving the last digit (7) to the front of it, giving us 714285.
|
||
It can be verified that 714285=5×142857.
|
||
This demonstrates an unusual property of 142857: it is a divisor of its right-rotation.
|
||
Find the last 5 digits of the sum of all integers n, 10 < n < 10100, that have this property.
