# why is two the only even prime number

In the integers, $-2$ is another even prime. For variety, in the Gaussian integers, $2$ is not prime: e. g. factors as $(1+i)(1-i)$. The even primes of the Gaussian integers are $pm 1 pm i$, although these are all the "same" prime in the same sense that in the integers, $2$ and $-2$ are the "same" prime. In the ring of all rational numbers with odd denominator, $2/7$ is an even prime.

In fact, $2/n$ is prime for every odd integer $n$. (but again, these are all the "same" prime)

There are also number rings that have distinct even primes that are not the "same" in the sense implied above. Is "0" a prime number? The number zero is not a prime number. By definition, a prime number dictates that the number must be a whole number greater in value than one and must be.

Is "111" a prime number? The number 111 is not a prime number. For a number to be considered a prime number, it cannot be divided by more than just itself and the number one. The n. Is the number 37 a prime number? The number 37 is a prime number.

The definition of a prime number is any positive number that can only be divided by the number one or itself. A prime numb. What are all of the whole number factors of 64? The number two is the only whole number factor of 64 because factors must be prime numbers, and all of the divisors of 64 except for the number one are div.
