title: Factor large numbers in Matlab and then get the numbers in the result
body: <p>I want to factor (<a href="https://oeis.org/A227960" rel="nofollow">these</a>) large numbers, and Matlab does that perfectly well.
  (<a href="http://pastebin.com/raw.php?i=t8eFAVZi" rel="nofollow">These</a> are the results.)</p>
  
  <p>The result of factor(NumberOfTypeSym) is another symbolic object:</p>
  
  <pre><code>&gt;&gt; factor( sym('79228162514264337589248983040') )
  
  ans =
  
  2^32*3*5*17*257*641*65537*6700417
  </code></pre>
  
  <p>But I can't do anything with that, except look at it.</p>
  
  <p>Is there any way to access the single primes and exponents?</p>
  
  <p>(It is beyond my comprehension, why they won't just give me an nx2 matrix, with the primes on the left, and the exponents on the right side.)</p>
  
  <p>What I especially need at the moment is the number of primes in the result, i.e. the sum of all exponents.</p>
