A friend and I had a lengthy debate about whether or not 1 was a prime number. My friend defined a prime number as a whole number that cannot be divided by another whole number and result in a whole number.

I then argued that 7 wasn't a prime number because it could be divided by 7 and result in a whole number. Then, he argued divided by another whole number other than itself or 1 and result in a whole number.

Anyways we reached a stalemate. I said -5,-3,-,2,-1, 1, 2, 3 ,5 , and 7 were prime numbers. He said -5, -3, -2, -,1, and 1 were not prime numbers, but 2 ,3, 5, and 7 were.

So who was right, is one a prime number? I say it is. Since if you divide one by 3 you get 1/3 which is not a whole number.

One is not a prime number. A prime number is a natural number (positive integers (whole numbers)) greater than 1 that has no positive divisors other than 1 and itself. By this definition, negatives can not be prime. Some examples are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 101, 103, 107, and 109.

bah, your right by definition 1 isn't a prime number. Seem arbitrary that one would be left out. I mean two is a prime number and its right next to one. There seems no good reason that one isn't a prime number. Also, don't understand why negative numbers can't be prime. Again, seems arbitrary.

negatives cannot be prime because they can be divided by a negative number, 1 and a positive number

The fundamental theorem of arithmetic states that any integer greater than one has a unique factorization of primes. If one is a prime, this longer holds, therefore one is not defined as a prime

Sorry I forfeited that other debate; I got super busy and never got to it. Now it'll be stuck in limbo for ages.

I would otherwise take this debate, as I take anything math related.

Simply put, one is not a prime number, since the definition of "prime number" is any integer that is greater than one, whose only positive integer divisors are itself and 1. So, by definition, 1 is not prime.

It seems that you're both right/both wrong as one is apparently neither prime nor composite.
