The positive integer with only one factor is 1.
2 is the smallest prime factor of 12.

If a number is not prime- that is, if a number has a positive factor besides one and itself- it is a composite number.
The least common factor of any set of positive integers is 1, and 1 does not have a prime factorization.
A factor can or cannot be a prime number Ex: 2 is the factor of all other even numbers its a prime number but 9 is a factor of 18 and its not a prime number A prime is a factor but a factor being a prime number varies
A prime number has two positive integer factors, itself and 1. The number 0 has no positive integer factors, and is therefore not prime. The number 1 has just a single positive integer factor, and once again, is not prime.
The definition of a prime is an integer that has two positive factors, one and itself. These are two distinct factors. One only has one positive factor. Thus it's not a prime.
47 - 2 = 45
A factor is a number or algebraic expression by which another is exactly divisible. A prime number is a positive integer with two factors: one and the number itself.
A multiple of 13 will be a composite number. Because the number will have 13 as a factor, it cannot be a prime number.
The least common factor of any set of positive integers is 1. The least common multiple of relatively prime numbers is their product.
