Record-Breaking Prime Number Discovered: How a GPU Army Found a 41-Million-Digit Behemoth
A New Champion in the World of Prime Numbers
The mathematics community is celebrating the discovery of a new largest known prime number—2¹³⁶,²⁷⁹,⁸⁴¹ − 1—a staggering 41,024,320-digit behemoth that surpasses the previous record holder by 16 million digits. This monumental find was achieved not by a supercomputer at a prestigious university, but by an amateur mathematician leveraging the power of graphics processing units (GPUs) in an unprecedented distributed computing effort.
Key Facts About the Discovery
✔ 16 million digits longer than the previous record (2018)
✔ 52nd Mersenne prime ever discovered
✔ Found using 24 data centers across 17 countries
✔ Discovered by Luke Durant, a former NVIDIA engineer
✔ Earns a $3,000 prize from the Great Internet Mersenne Prime Search (GIMPS)
“It was a pretty big surprise, but I had been working hard to grow the system. I joined to learn about big math, showcase GPU capabilities, and support the GIMPS community.”
— Luke Durant, Prime Discoverer
The Science Behind the Search
What Makes Mersenne Primes Special?
Mersenne primes take the form 2ⁿ − 1 and have unique properties that make them:
- Easier to verify than general primes
- Rare gems in number theory (only 52 known)
- Linked to perfect numbers (a separate mathematical curiosity)
Why GPUs Revolutionized the Hunt
Traditional prime searches used CPUs, but Durant’s GPU-based approach offered:
- Massive parallel processing (thousands of calculations simultaneously)
- Energy efficiency compared to CPU clusters
- Cost-effectiveness for large-scale computations
