In a groundbreaking development for mathematics and computer science, the Great Internet Mersenne Prime Search (GIMPS) has announced the discovery of the largest known prime number. This monumental find, made possible by harnessing the power of cloud computing and graphics processing units (GPUs), marks a significant shift in how mathematical research is conducted.
The New Prime Number
The newly discovered prime number, 2^136,279,841 - 1, boasts an astounding 41,024,320 decimal digits. To put this into perspective, if printed in standard font size, it would stretch over 13 miles long. This Mersenne prime, named M136279841, dwarfs its predecessor by more than 16 million digits.
A Paradigm Shift in Prime Number Discovery
What makes this discovery particularly noteworthy is the method used to find it. Unlike previous Mersenne primes found using traditional CPUs, this prime was discovered using GPU technology. Luke Durant, a 36-year-old former NVIDIA employee, leveraged his expertise in GPU design to create a cloud supercomputer comprised of thousands of server GPUs spread across 24 datacenter regions in 17 countries.
Durant's approach demonstrates the potential of GPUs beyond their typical applications in artificial intelligence and graphics rendering. By utilizing cloud infrastructure and specialized software developed by Mihai Preda (GpuOwl), Durant was able to harness unprecedented computational power for mathematical research.

The Discovery Process
The journey to this discovery began in October 2023 when Durant started contributing to GIMPS. After nearly a year of testing, success came on October 11, 2024, when an NVIDIA A100 GPU in Dublin, Ireland, reported a probable prime. The primality was confirmed the next day by an NVIDIA H100 in San Antonio, Texas.
Verification and Collaboration
The discovery sparked a collaborative effort to verify the prime number using various methods and hardware. This process involved running multiple primality tests using different programs on CPUs and GPUs, showcasing the importance of diverse computational approaches in mathematical verification.
Implications and Future Prospects
While the practical applications of such large prime numbers remain limited, the discovery process itself has significant implications. It demonstrates the potential of cloud computing and GPU technology in tackling complex mathematical problems. Moreover, it opens up new possibilities for distributed computing projects and citizen science initiatives.
The search for even larger Mersenne primes continues, with GIMPS inviting anyone with a reasonably powerful PC or GPU to join the hunt. This democratization of scientific discovery could lead to further breakthroughs in mathematics and computer science.
Funding and Recognition
The discovery has raised questions about the funding behind such intensive computational efforts. While Durant is eligible for a $3,000 research discovery award from GIMPS, which he plans to donate to a math department, the scale of the computing resources used suggests potential backing from larger entities, possibly including GPU manufacturers interested in showcasing their hardware's capabilities.
As we marvel at this mathematical milestone, it's clear that the intersection of advanced hardware, cloud computing, and collaborative research is paving the way for future discoveries in fields far beyond prime number searches. The success of GIMPS and Durant's innovative approach may inspire similar projects, further blurring the lines between professional research and citizen science.
