Number factorisation using Yafu
<p>I am trying to use Yafu to factorize RSA Keys.
One thing that surprises me is Yafu shows more than 2 factors even though RSA keys should have only 2 factors. Why is this so?</p>

<p>For example, when I factor the following no:</p>

<blockquote>
  <p>factor(1522605027922533360535618378132637429718068114961380688657908494580122963258952897654000350692006139)</p>
</blockquote>

<p>I get these as factors:</p>

<pre><code>  P2 = 11 
  P7 = 6698689 
  P8 = 18633149 
  P12 = 407893628797 
  P22 = 4702659209804290841741 
  P50 = 57813341690015577934703993485336625998708275892717
</code></pre>
