Primality proof for n = 5336643803:
<p>Take b = 2.
<p>b^(n-1) mod n = 1.
<p><a href=13037.html>13037 is prime.</a>
<br>b^((n-1)/13037)-1 mod n = 545201552, which is a unit, inverse 3693013844.
<p><a href=4177.html>4177 is prime.</a>
<br>b^((n-1)/4177)-1 mod n = 832831245, which is a unit, inverse 5315758707.
<p>(4177 * 13037) divides n-1.
<p>(4177 * 13037)^2 > n.
<p>n is prime by Pocklington's theorem.
