Primality proof for n = 2707:
<p>Take b = 2.
<p>b^(n-1) mod n = 1.
<p><a href=41.html>41 is prime.</a>
<br>b^((n-1)/41)-1 mod n = 631, which is a unit, inverse 2278.
<p><a href=11.html>11 is prime.</a>
<br>b^((n-1)/11)-1 mod n = 1084, which is a unit, inverse 452.
<p>(11 * 41) divides n-1.
<p>(11 * 41)^2 > n.
<p>n is prime by Pocklington's theorem.
