solutionsThere are exactly four positive integers such that is an integer. Compute the largest such ni only found negative solutions I see you have graph paper. You must be plotting something #2 20131116 12:49:00
Re: solutionsFor that to be an integer, 484 must be divisible by (n+23).

Re: solutionsThis is an integer if and only if 484 is divisible by n+23. The factors of 484 are ±1, ±2, ±4, ±11, ±22, ±44, ±121, ±242, ±484 so there are 18 solutions altogether. The positive ones are given by n + 23 = 44, 121, 242, 484. 134 books currently added on Goodreads
