Definiton from Wikipedia....(read very carefully Outhouse)

A natural number (i.e. 1, 2, 3, 4, 5, 6, etc.) is called a prime number if it has exactly two positive divisors, 1 and the number itself.

****

....and since 1 can be legally divided by itself, it therefore is a prime number also.

This null & voids, shoots down, and embarrasses a) in quote #49. 

Very weak trolling.

A prime number (or a prime) is a natural number greater than 1 that has no positive divisors other than 1 and itself

https://en.wikipedia.org/wiki/Prime_number

And don't even try to edit, the page; unlike you, I am not stupid. Your stubborness and your childish behaviour only embarrass yourself.

P.D. Your own definition "A natural number (i.e. 1, 2, 3, 4, 5, 6, etc.) is called a prime number if it has exactly two positive divisors" also excludes number 1. Learn to read.


Keep posting if you wish, you will be ignored, as this has been made pretty clear.

The number 1 is a special case which is considered neither prime nor composite (Wells 1986, p. 31). Although the number 1 used to be considered a prime (Goldbach 1742; Lehmer 1909, 1914; Hardy and Wright 1979, p. 11; Gardner 1984, pp. 86-87; Sloane and Plouffe 1995, p. 33; Hardy 1999, p. 46), it requires special treatment in so many definitions and applications involving primes greater than or equal to 2 that it is usually placed into a class of its own. A good reason not to call 1 a prime number is that if 1 were prime, then the statement of the fundamental theorem of arithmetic would have to be modified since "in exactly one way" would be false because any n=n·1. In other words, unique factorization into a product of primes would fail if the primes included 1. A slightly less illuminating but mathematically correct reason is noted by Tietze (1965, p. 2), who states "Why is the number 1 made an exception? This is a problem that schoolboys often argue about, but since it is a question of definition, it is not arguable." As more simply noted by Derbyshire (2004, p. 33), "2 pays its way [as a prime] on balance; 1 doesn't."

With 1 excluded, the smallest prime is therefore 2. However, since 2 is the only even prime (which, ironically, in some sense makes it the "oddest" prime), it is also somewhat special, and the set of all primes excluding 2 is therefore called the "odd primes." Note also that while 2 is considered a prime today, at one time it was not (Tietze 1965, p. 18; Tropfke 1921, p. 96).

Dontchu feel kinda sorry for one ?....I mean look what it represents ! Nothing very good can ever come outta loneliness....unless you're doing a one-hour self-assessment....or swimming. I say give it some latitude & extend it it's day in the sun. It deserves it !

So. From gromius above, the #1 is obviously contentious. IOW's, by its very nature ?....1 is definitely prime. Who can argue that ?....but it sounds like the current generally accepted convention (that could change !) has labeled it not a prime number. But why ?....to avoid confuzion ?....I guess so. But that doesn't sit well w/ me at all.

Funny how "arithmetic convention" DOES NOT isolate the #2. Disciminatory. That's how I feel.

And 'cuz some commission got together & ruled the #1 wasn't prime ?....well, doesn't make it so.

I mean use your imagination. If you were first presented w/ all this ?...wouldn't you too conclude the #1 was prime too ?....& don't lie.

One is the loneliest # that I ever knew. Two can be as bad as one....it's the loneliest # since the # one.

....and the most important sentence that gromius makes above is the last "one".

all the other numbers are made of ones added together. one is everywhere. we are all one.

....u have two 1's in your username....I luv it....the best things come in pairs Smile !

....and if zero doesn't count for anything (when does it ?) all your username numbers are prime #'s....yay !

odisea777

yeah, good point. did not notice. I think a and b are prime letters too

The_Ghostess_Lola

If a and b are prime letters ?....then what would be a subprime letter ?

....just curious.
