Two New Mathematical Theorems Relating to the Factorial Content of Certain Integers

For any given odd integer that does not contain the integer 5 as a factor, there exists an infinite number of integers (consisting only of digit 9’s, e.g., 999999…) which contain this given odd integer as a factor. Continue reading…

Some Companion Conjectures to Goldbach’s Strong Conjecture

The even integers from 4 to 28 as sums of two primes. Goldbach's conjecture states that every even integer greater than 2 can be expressed as the sum of two primes. Image: Wikipedia.

Goldbach’s Strong Conjecture is the following: Every even integer greater than 2 can be expressed as the sum of two primes. Continue reading…

The “Long Sought”, Practical Prime Number Formula Has Been Known (But Not Recognized as Such) Since Ancient Times

The search for a simple and easy to use formula, that would produce integers guaranteed to be prime, has gone on since ancient times. It appears that no one ever happened to notice (until I did) that a type of equation which has been known since ancient times, will produce integers that are guaranteed to be prime, if the equation is set up properly. Continue reading…
