The prime factors are 13, 3, 2, 2, 2, and lots more 2s
So you can divide this by 2, 4, 8, 16 and so on and also by 3 and 13.
I always look at the prime factors when I see and oddball number like
this.  (There are web sites to help factor numbers)

I have one of these on order.  I'm sure it will be used one day to
clock a DDS chip.   There really is no reason to clock a DDS with a
nice even number frequency.  OK the even freq. makes the math easier
but it's all done in software so "easier" does not matter.
