 Forum: Factoring 2022-08-09, 15:59 Replies: 24 Views: 1,550 Posted By Viliam Furik I have gone through the prime powers from p^2 to... I have gone through the prime powers from p^2 to p^9, manually on paper (quite easy, and I could have done more, but I decided to rather make the program for this). I have found that they all end in...

I've made a program that calculates the next number according to the rule n * d(n) / (gcd(n, d(n)) ^2), and run it for all numbers smaller or equal to 1,000,000. For every number, it calculates its...

Well, it only uses division by 2, which can be done as a right-shift, and addition and value comparing, so if it works as intended, then I believe it is much faster - at least algorithmically, as it...

If the square number is even, it must be divisible by 2, and also 4, as all powers of prime divisors of squares must be even for it to be a square number. If you take a square s...

Under my gcd rule, 9 goes to 3, not 18 (while doing those first few numbers in my head, I probably forgot to add 1 to the power 2 in...

The conjecture originally was that these prime loops (p -> 2p -> 2p) are the only loops and that all numbers terminate in such a loop. @henryzz pointed out more formats (actually a pattern for...

I was explaining my improved version of the original rule for the sequence. Thus 75 goes to 50. At least in my version, that is. 75 = 3 * 5^2, that is 6 divisors, 6 = 2...

For a moment I thought about using only the proper divisors, but this lead me very quickly to a realization of a problem with primes, which would then have only 1 divisor. These number series are...
