Let SS be the sum of all numbers of the form ab,\frac ab, where aa and bb are relatively prime positive divisors of 1000.1000. What is the greatest integer that does not exceed S10?\frac{S}{10}?


Leading zeroes must be inputted, so if your answer is 34, then input 034. Full credit goes to MAA for authoring these problems. These problems were taken on the AOPS website.
