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

By definition, all prime numbers have exactly two factors. There is not a prime number that has only one factor.

a prime factor

It is 1 which is neither a prime nor a composite number

prime * * * * * No, the only number with just one factor is 1. Each prime has TWO factors: 1 and the prime itself.

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.

2 is a prime number because its only factors are one and itself. Since 2 is a prime number, if it is a factor of your number, it is a prime factor.

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.

Squares (or cubes or more) of prime numbers have one distinct prime factor, but if you're counting them individually, all composite numbers have at least two prime factors.

The answer depends on whether or not the prime number is a factor of the other number.If the prime number is a factor of the other number then the GCF is the prime, otherwise the GCF is 1.
