Is there a special reason why the "40" and "72" are missing in this line ?
If they would exist, the numbers may be seen as a symmetrical object with 
its "half" between 18 and 20.

> 3,4,5,6,8,9,10,12,15,18,20,24,30,36,(40),45,60,(72),90,120

with 360/N

120,90,(72),60,45,40,36,30,24,20,18,15,12,10,(9),8,6,5,4,3


Therefore it probably could increase the "randomness" if You chosse to 
calculate two random values:

the first one to choose from an array(N), with only the first ten numbers 
in it, as described by many earlier.

the second random value as RND(2) which chooses the number N from the 
array directly as the result if it is "1", otherwise, if it is "2", the 
result is calculated as 360/N.
