One is not a prime number. A prime number, by definition, is a number that is only divisible by two numbers: one and itself. One is divisible by only one number, one, and therefore is not a prime number.

No 1 it is not a prime number. The definition of a prime number is that it can only have factors of one and itself. Since one already has one then it can not be a prime number.

one is in fact a prime number.

one is not a prime number because one isn't divisible by 2 diffrent numbers it is only divisible by one number one which is itself

A prime number is a number that has only two factors which are itself and one

2 is one prime even number.

A prime number only has two factors: itself and the number one. You get the prime number, your opponent gets one.

no, but I don't know why. One is not a prime number and by definition of a perfect number one must be a prime number.

No, a prime number is only divisible by itself and one. And since one doesn't count as a prime number, no.

No. The only even prime number is 2.

True. By definition, a prime number is divisible by one and by itself. Also by definition, a perfect square has at least an additional pair of factors - it's square root. Therefore a prime number could never be a perfect square. One exception that might come to mind in this case is the number one. One however, is not considered a prime number, and thus does not conflict with this rule.

A prime number.

A prime number has only one prime factor, and that prime factor is the number itself.

The largest prime number yet discovered has 17,425,170 digits. That does not have a specific name. Perhaps you could come up with one.

There is no "the" prime number. 2 is one of the prime factors of 46.

a prime number is a number that you can plus by one

This is impossible. A prime number is defined as a number that is only divisible by one and itself. Thus, a 'prime' number capable of being divided by another prime number is by definition not a prime number.

No prime number only has one factor. Each prime number has itself and 1 as factors. Now, the number 1 of course has only one factor, but it is technically not a prime number.

241 is a prime number. Any number that only has itself and one as factors is a prime number. Therefore, since there are no factors of 241 other than one and itself it is a prime number.

One is neither prime nor composite. For a number to be prime, it can only be dividable by 2 numbers. One is only divisible by one number, 1.

Multiples of 6 are even. The only even prime number is 2.

A prime number is a number which can only be divided by one or the number itself. The number 22 can be divided by one, two, eleven and 22. Thus, it is NOT a prime number

A prime number can only be divided by itself and one, therefore 741 is a prime number.

well of course there are and infinite number of prime numbers there is not only one. If you thinking of the number 1, the number one is not prime because the definition of a prime number is that it must not have any multiples except one and itself. Since a number cannot have a multiple of itself that is the same number 1 is not prime
