Try dividing it by every prime below fifty. You'll find out whether you're right or wrong...

And one other, but if you want to find that one, just divide your original number by (29*43).

I didn't even type FactorInteger...

If you type in 1466996987 into the input box, it will give you all kinds of properties about the number... including prime factorization.

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.
