COMMENTS

Comment from J. Lowell: Regular polygons with n sides in which internal angles have integral number of degrees (n >= 3).

360 is a highly composite number: A002182(13) = 360. - Reinhard Zumkeller, Jun 21 2010

There are 22209 ways to represent 360 as a sum of its distinct divisors (A033630). That's more than any smaller number, hence 360 is in A065218. - Alonso del Arte, Oct 09 2017
