Mersene Prime and Number Theory
I have found and tested number, it is has 894,424,861 digits.In my tests it shows this number is a prime. Can anyone help me to verify the primality of this number? The prove and disprove of the primality of this number will be important to number theory.
Thank very much... I can also be contacted in my email address is rcdbulanhagui@yahoo.com .

894,424,861 digits imply you mean 2^{2,971,215,073}1, but it has a factor: 58547736275141965993, so it can't be prime.

If someone finds your number is actually prime, then the terrorists will have won. There are no "tests" that can show whether that number is a prime with our current hardware. The fact that you can't even spell "Mersenne" shows you are completely ignorant. You are only trying to draw attention to yourself.

2971215073 is a factor of Fib(423). Why the compositeness of its corresponding Mersenne matters is a question that only Ricie can answer.

Now, now, 10metreh. Cranks (like Ricie) cannot give substantial evidence for their claims (hence the name crank). Furthermore, due to Ricie's lack of verbosity I doubt that he even possesses the ability to answer questions coherently.

( logic ) if they have never won and have not 10metreh formula, 10metreh then be like them ... Last fiddled with by cmd on 20090813 at 21:56

It seems quite evident (to me, at least) that English is not Ricie's first language. Supposedly deducing a lack of mental ability on the basis of some minor errors in written English by a nonnative speaker/writer says more about the deducer's state of mind than it does about the person making the visible errors. This bad habit is far too common on this forum, and it's been far too long since I last complained about it. I ask those who would make such comments: How errorfree and colloquially can you write online in a nonnative language? How would you feel if you posted a sincere question in a "second" language, then saw a native user of that language make such comments about you, ridiculing your mental ability because of some grammar or spelling mistakes? Ricie may or may not have a sound mathematical idea, but confusing (a) the awkwardness in which it is phrased in a nonnative language with (b) the unsoundness of the idea does nothing to help Ricie understand what is or isn't correct mathematically.

HOWEVER, if he could phrase his questions better, then that would be beneficial for both Ricie and other members of this forum. Last fiddled with by flouran on 20090814 at 00:37

Where are they, again  the posts where, after being informed of being wrong, Ricie demonstrates unwillingness to admit wrongness? Please provide links.
