All numbers, (except 1) have at least two factors: 1 and the number itself. So, there are no numbers, besides 1, with only 1 factor. And 1 is neither prime nor composite.
Composite
When a composite number is expressed as the product of its prime factors, we call that the prime factorization.
composite number
There is no name for such numbers.
The property of prime or composite is not defined for the number 1, just as it is not defined for any number that has a fractional part. There are no special names for numbers that are not prime nor composite.
a prime number
Just "one."
The number one only has one factor... 1. Prime numbers have two factors, and composite numbers have more than two factors. One is just... out there.
One.By definition numbers are:prime if they have only 2 distinct factors (namely 1 and the number itself);composite if they have 3 or more distinct factorsThe important thing to note is the word distinct. The number 1 has only 1 distinct factor, namely 1; thus it is neither a prime (the first prime number is 2) nor composite.
There is no specific name for such numbers.
