PrimeGrid's primary goal is to bring the excitement of prime finding to the "everyday" computer user. By simply downloading and installing BOINC and attaching to the PrimeGrid project, participants can choose from a variety of prime forms to search. With a little patience, you may find a large or even record breaking prime and enter into Largest Known Primes Database as a Titan!
PrimeGrid's secondary goal is to provide relevant educational materials about primes. Additionally, we wish to contribute to the field of mathematics.
Lastly, primes play a central role in the cryptographic systems which are used for computer security. Through the study of prime numbers it can be shown how much processing is required to crack an encryption code and thus to determine whether current security schemes are sufficiently secure.
PrimeGrid is currently running several sub-projects:
- 321 Prime Search: searching for mega primes of the form 3·2n±1
- Cullen-Woodall Search: searching for mega primes of forms n·2n+1 and n·2n−1
- Extended Sierpinski Project: helping to solve the Extended Sierpinski Problem
- Prime Sierpinski Project: helping Prime Sierpinski Project solve the Prime Sierpinski Problem
- Proth Prime Search: searching for primes of the form k·2n+1
- Primorial Prime Search: searching for primes of the form p#+1 and p#-1
- Seventeen or Bust: helping to solve the Sierpinski Problem
- Sierpinski/Riesel Base 5 Project: helping to solve the Sierpinski/Riesel Problem with base 5
- The Riesel problem: helping to solve the Riesel Problem
- Generalized Fermat Prime Search: searching for Generalized Fermat primes
- AP27 Search: Search for Primes with arithmetic progression

Project Staging Area
The PSA was created to research, test, and prepare future projects for PrimeGrid BOINC. It has also expanded to include additional projects that will not enter BOINC. While we attempt to do most of the prep work internally, some efforts are so large that we need the assistance of the community.
Sieving
- Generalized Fermat Number Prime Sieving (paused)
There are currently no active sieving projects in the PSA.
PRPNet
There are currently no active PRPNet projects.
