# Rory's Prime

Jan 30, 2016 — 1 minute read — # Math # ComputeOne day I decided I want to discover a prime number of my very own.

After a bit of research, and **203.53 quadrillion** floating-point operations later, I became the proud father of:

## 5687 · 2^{1376451} + 1

a **414,357 digit-long** titanic Proth Prime! As of `1/29/2016 06:20:31 CDT`

, this is the **2,261 ^{st} largest prime ever discovered!**

Raw decimal representation: rorys-prime-decimal.txt

This Proth Prime Search was done in collaboration with the Proth Search project. This search looks for primes in the form of k · 2^{n} + 1, with the condition 2^{n} > k. These are often called Proth primes.

Thanks to the PrimeGrid project and BOINC for making this pretty easy to get started!
