Primality proof for n = 379795560371:
<p>Take b = 2.
<p>b^(n-1) mod n = 1.
<p><a href=18413.html>18413 is prime.</a>
<br>b^((n-1)/18413)-1 mod n = 306896679354, which is a unit, inverse 242678902243.
<p><a href=1583.html>1583 is prime.</a>
<br>b^((n-1)/1583)-1 mod n = 173019972171, which is a unit, inverse 272941825608.
<p>(1583 * 18413) divides n-1.
<p>(1583 * 18413)^2 > n.
<p>n is prime by Pocklington's theorem.
