A longgg time ago this question was discussed here on the forums. Click here to get BsOdOriginally Posted by Judi
According to the thread those are the numbers that are powers of two. Thus, 32 is the answer cuz,
$\displaystyle 32=2^5$
I haven't come up with a proof for it, I just used logic, but I found that if a number is not divisible by any odd number, than it has no solution of consecutive integers. (I'm not sure if thats the same as saying if a number is a power of two or not)Originally Posted by ThePerfectHacker
[EDIT] Actually, they are the same thing.
