just times it by 15 to start of with
Okay first we guess the ratio of the two primes, right?
Like, maybe it could be a ratio of

"""(the reason why sahould be fu^king obvious!)"""
lol then why didnt he divide by 15 and times by 3 and 5
oh i forgot its so obvious

No, he's completely correct. It really is very easy to factor a number right after you create it by multiplying two carefully chosen primes.
Now if only there was some way for him to force bitcoin to use RSA instead of ECDSA. And some way for him to force people to randomly generate shitty primes for their keys.
Now if only there was some way for him to force bitcoin to use RSA instead of ECDSA. And some way for him to force people to randomly generate shitty primes for their keys.
See http://en.wikipedia.org/wiki/Crank_(person).
He is basically saying that if you have and you know to very high precision the ratio you can find p and q. Well, duh, p=(nr)^0.5 and q = (n/r)^0.5. You do not in general know the ratio, and there is no known efficient way to factor an arbitrary integer.
If that person's method is as good as he thinks, he is welcome to try to factor RSA-2048.

Can someone please poke some holes in this:
Again, this is not my claim, I am merely posting it so people can take it apart. I'm sure there are some obvious flaws, but I don't follow the post's math nor the actual bitcoin math well enough to see them clearly.
Thanks.

A word of caution, there is still a long standing myth that factoring dual-prime composite numbers is asymetrically complex, and that no simple algebraic method exists that can factor them in polynomial time.
http://primes.utm.edu/lists/small/10000.txt
I am going to deliberately choose two prime numbers that are almost exactly to the ratio 3:5 ( for illustration purposes only!)
Here is the dual-prime composite :- 1851437057
Now let’s multiply it by 15, (the reason why sahould be fu^king obvious!)
1851437057 x 15 = 27771555855
166647.99985298353409097666564141 the square root by Windoze Scientific Calculator…Gosh! surprise! suprprise” NOT it’s almost 166648 (How number of the Beastly!)
166648 x 166648 = 27771555904
27771555904 – 27771555855 = 49 = 7 x 7.
166648 + 7 = 166655 & 166648 – 7 = 166641,
166655 obviously divides by five, 166655/5 = 33331
and 166641 slightly less obviously divides by three, because the sum of the digits also divide by three! 166641/3 = 55547 so 55547 x 33331 = 1851437057
The moment we discover the ratio of the two prime numbers that compose the composite dual-prime, the fu^king game is over! And please believe me, any competant mathematician would NOT find that little task in the least bit complicated!
Arbitrary Precision Calculator Software will factor large dual-prime composite numbers in milliseconds! Trust me on this assertion!
Now go to Wikipedia and look up how Bitcoin Security functions. Do you fancy holding a bag of rotten eggs in a wet brown paper bag? … because that wet paper bag is more secure than Bitcoin’s Security. CAVEAT (from The Royal Military Police, Surveillance Division)
