Try dividing it by every prime below fifty. You'll find out whether you're right or wrong...
 
  • #3
thank u
its divisible by 29,43
 
  • #4
And one other, but if you want to find that one, just divide your original number by (29*43).

Yeah. I should have known. There was method to my madness. I used Mathematica Information to find the operator used to factor primes, then figured Worlframe Alpha would recognize it too.

I just tried factor 1466996987 from command line. But even factor(1466996987) on TI-89 gives answer almost immediately.
