.: Prime Factors Testimonials :.

The Prime Factors software is all that I need and much more. I find your software helpful and I appreciate you taking all the time for me personally.

I have been using the software since 2005, mainly to assist in the solving of difficult numerical puzzles. I have found it very easy to use and results are displayed very quickly. An admirable single-purpose program.

I've been using Prime Factors almost daily since purchasing a license 3 years ago. It's an invaluable factorization tool for analyzing prime number sequences and related patterns.

Prime Factors is fantastically useful and very entertaining software, especially if you're into prime numbers! Identifying prime numbers and counting the number of them in any range is child's play and the factorizing is lightning fast! Identifying twin primes and counting the number of them in any range is also incredibly easy! Perhaps future updates of the software would make other prime constellations as easily searchable! And an increased absolute range would also be icing on the cake! I recommend this software wholeheartedly! Enjoy!

Prime Factors is the most efficient and feature-rich prime factorization software I have seen. It's in a class by itself.

As both a professional IT Manager and an application developer I constantly find myself needing mental stimulation. I use mathematics as a way to quench that thirst, yet spending hours and hours in an Excel grid to calculate factors in a way that was visually understandable was defeating. I discovered Prime Factors simply by browsing applications on the web and instantly knew I had to have it. This program will keep the wheels turning for many more years.

As a cryptographer and author currently working on a complex series of codes designed during the 16th, 17th, 18th and 19th centuries I use Hermetic Systems' Prime Factors virtually every day to help analyze numerical occurrences for primes as well as factors which then relate to specific encryptions or to locations where other encryptions are to be found. This software is absolutely invaluable to me and I can honestly say I would be lost without it. I must also compliment Peter Meyer on using very fast factorizing alogorithms. In comparison to other software his program is 'simply the best'.

I am amazed at the possibilities that Prime Factors offers. Not only can you find primes, prime pairs and prime factors easily, but you can also graph the distribution of the number of prime factors — something I haven`t seen elsewhere. And probably most valuable for research is the ability to filter for primes that fulfil a user-specified formula.

As the inventor of Global Numerics, a predictive system attempting to explain why one day is different or similar to the previous or following one, I highly recommend Peter Meyer's Prime Factors. This software, in fact, made its discovery possible. It is an invaluable tool for computing daily prime number sets. No doubt it has other great features for which I have no use, but it is more than adequate for my needs and very affordable. Prime Factors is worthy of serious consideration.
