Primality proof for n = 3572919677:
<p>Take b = 2.
<p>b^(n-1) mod n = 1.
<p><a href=937.html>937 is prime.</a>
<br>b^((n-1)/937)-1 mod n = 690486337, which is a unit, inverse 2565679398.
<p><a href=383.html>383 is prime.</a>
<br>b^((n-1)/383)-1 mod n = 1168562122, which is a unit, inverse 602762945.
<p>(383 * 937) divides n-1.
<p>(383 * 937)^2 > n.
<p>n is prime by Pocklington's theorem.
