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.

Once all the prime factors of a number have been found, the number of factors the number has and what they are can be found. I'd be finding the prime factors first before finding all the factors of a number, so I'd rather find all the prime factors as it means I can stop before I have to do more work in finding all the 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 only has two factors. If the number you're looking at has more than two factors, it is not prime.
