I assume you are asking how do you work out the factors of a prime number. A prime number by definition only has itself and 1 as factors.
Work out if they have any factors, other than the number 1 and themselves. If they do not they are prime.
Prime numbers have two factors. Prime squares have three factors. Square numbers have an odd number of factors but that number varies.
Well, the factors of a prime number is that they only have two factors.
Basically, a factors of a larger number are the factors which theoretically 'make up' the number. Factors are the prime numbers when multiplied together, give the final product. e.g. 2x2x2x2x2 are the prime factors of 32 as 2 (prime) is the simplest form. However, when the number for example is 7, there is only one factor as 7 is a prime number itself.
There is not such a thing as a composite prime number. A prime number has exactly two factors. A composite number has more than two factors.
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.
A prime number has two factors: one and the number itself. A prime number does not have any proper factors.
Whether a number is a prime number or not is determined by its factors. It is a prime number if its only factors are 1 and itself.
You cannot list all the potential prime factors. Any prime number can be a prime factor. There are an infinite number of prime numbers, so there are an infinite number of potential prime factors. If given a specific number, the prime factors for it can be listed.
The prime factors of a squared number are the prime factors, if any, of its square root.
Prime numbers have as factors the number 1 and their own number. Example: 37 is a prime number because its only factors are "1" and "37". If the prime number had further factors, it would no longer be prime.
