First, zero is not applied to the terms prime and composite because the definitions only apply to natural numbers (positive whole numbers, which does not include zero). One is not prime or composite because one is the unit that is used within the definition of prime of composite numbers, and many definitions of prime and composite even exclude one from the definition. If you want to categorize one within a discussion of prime and composite, it is common to simply call one the unit.

Not at all. The definition of a composite number is one that has more than two factors - the exact opposite of a prime.

Being divisible by numbers other than itself and 1 means it's not prime. It therefore is composite by definition.

Prime numbers have two factors.

Composite numbers are used to factorize a number into smaller. It makes calculation easy for the person.

A composite number is a positive integer that has a positive divisor other than one or itself. In other words a composite number is any positive integer greater than one that is not a prime number.

You could try dividing by composite numbers but the number that you are testing is divisible by a composite number, then it will be divisible by a prime factor of that composite number and that prime factor will be smaller. It is always easier to work with smaller numbers.
