Why is one a prime number?
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.
Is there a remainder when you divide a prime number?
Yes, unless you divide the number by itself, then the answer would be one. Also, you can divide it by one, and the answer would be that number.
Is 74 prime number?
No It is not a prime number. There are two ways you can tell its not prime. First of all, their is only one even number that is prime, and the number would be 2. Second, 74 is a composite number, therefor it cannot be prime. Hope it helps you a bit :)
Is the number one a prime factor?
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.
Can a prime number also be a square number?
No. To be prime it has to be divisible only by itself and one. That means that no numbers multiply to be it. The only possible exception is one. In the math world it may have been decided whether or not one is a prime number, but that is debatable and I'm not aware of the answer. If 1 was considered a prime number, then it would be the only prime square.
Is 13 prime or composite?
13 would be considered a prime number, because it can only be divided by one and itself.
Is the square of a prime number a prime number?
No, never. It would be divisible by the prime number.
Would a 5 in the one place still be a prime number?
Not unless the number is 5.
Are there any prime numbers divisible by 2?
Yes there is only one prime number that s divisible by 2. That is 2, itself, because a prime number is a number that is evenly divisible only by itself and the number one (1). Any other number divisible by 2 would not be a prime number.
What is a prime number less than 17?
It would be 13, since the definition of a prime number is "Any number who's only factors are one and itself".
What number has only one prime factor?
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.
Can a prime number end in 5?
5 itself is a prime number, so if you count 5 as ending in 5 that is one prime number. Other than that any number ending in 5 would be some multiple of 5 and therefore could not be a prime number.
Why do you get a prime number answer to a prime number question?
The question is tautological. If the answer was not a prime number then thye question would not be called a prime number question!
Is 1755 a prime number?

Would a consecutive number be a prime number?
No, it would not.
Is one a perfect number?
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.
Prime factorization of 19?
