| title: 'Problem 168: Number Rotations'
 | ||
| ---
 | ||
| 
 | ||
| ## 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.
