A Prime number is a number that only has two factors. That is, it can only divide evenly (without leaving a remainder) by 1 and itself. 21 can divide by 3 to give 7. Therefore it has more factors than just 1 and itself. Thus twenty-one is not a member of the prime number set.
A prime number is a number that only has two factors. That is, it can only divide evenly by 1 and itself. 17 cannot divide by any number in between 1 and itself. Thus it has only two factors. Therefore 17 is a member of the prime number set.
2 is the only member of both the set of all prime numbers and the set of all even numbers.
It is the set {2}.
The 20th prime is 71.
No it is not. By definition, a prime number must be a natural number. Negative numbers are not in the set of natural numbers.

No, a prime factor is a single factor that is a prime number. A proper factor is a member of the set of factors that doesn't include one and the number itself.
0.2 is not a prime number. Prime numbers belong to the set of whole numbers.
2 is the only member of both the set of all prime numbers and the set of all even numbers.
It is the set {2}.
A number is relatively prime to another number or set of numbers when their GCF is 1.
All numbers have factors. Some factors are prime numbers. These are known as prime factors. The set of prime factors is a subset of the set of factors for any given number.
The 20th prime is 71.
The LCM of a set of prime numbers is their product.
A member of the set of its multiples.
By itself and 1 because it's a prime number
No it is not. By definition, a prime number must be a natural number. Negative numbers are not in the set of natural numbers.
