Highly Composite Numbers (Anti-Primes)
Thursday, December 6, 2018
By: Matthew Doucette

Highly composite numbers have more factors than any number smaller than themselves. In other words, they are numbers with a high degree of factorization or divisibility. This is the opposite of a prime number, which has no factors (other than 1 and itself).

Highly Composite Numbers (HCMs) and Factorizations:

1: 1.

2: 1, 2.

4: 1, 2, 4.

Prime Numbers Background:

This research is based off a posting I made a year ago about prime numbers and prime factorizations. At that same time, I was also exploring highly composite numbers.

Prime vs. Composite Numbers:

One way to think about prime vs. composite numbers is the following:

• prime numbers = the atoms of numbers
• composite numbers = the molecules of numbers

To put this in perspective, most numbers have very few factors. Check out the factors of numbers from 18,446,744,073,709,551,615 (the largest 64-bit integer; 2^64-1) and downward:

18446744073709551615: 3, 5, 17, 257, 641, 65537, 6700417.
18446744073709551614: 2, 7, 7, 73, 127, 337, 92737, 649657.

18446744073709551600: 2, 2, 2, 2, 3, 3, 5, 5, 7, 11, 13, 31, 41, 61, 151, 331, 1321.
18446744073709551599: 19, 67, 14490765179661863.
18446744073709551598: 2, 17, 17, 17, 2927, 641387128649.

Performance / Application Versions:

Highly Composite Numbers v0.3

• v0.1: November 14th, 2017:
• A quick C# application and about an hour's worth of runtime shows the first results, up to 554,400.
• v0.2: December 7th, 2018:
• I improved my program significantly with a fiew optimizations, and could reproduce the previous hours' work in 15 seconds.
• The main optimzation was to only search up until the square root of the number being factored, and pull out both factors. Such as, factoring 100 into 2 also gives you 50, and you only have to go as far as 10 -- the square root of 100. Note that 10 also gives you another 10, as 10 * 10 = 100, which you must ignore to avoid duplicate factors.
• v0.3: December 8th, 2018:
• "Graphical" and HTML output improvements, to help me blog the results.

Looking forward, I wish to get into multi-threading, it is something I have not coded for a long time. Not even our games were multi-threaded (to maintian simplicity), although they were highly optimized. The last time I coded multi-threaded algorigthms -- from memory -- was eScape. And that was in C++, helped by Jason Doucette.
