What about<br>
<br>
<pre wrap="">diff = x - x_base
if diff and gcd(diff, n) > 1:
return gcd(diff, n)
# or
</pre>
<pre wrap="">if (x - x_base) and gcd(x - x_base, n) > 1:
return gcd(x - x_base, n)
</pre>
and have the interpreter handle the optimization, or apply an
lru_cache? ;-)<br>
<br>
Cheers,<br>
