### What do you call a number that's neither prime or composite?

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 factors
The 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.

### Is 30 composite or prime?

30 is composite. A composite number is simply a number that has
more factors than 1 and itself. So since 3 times 10 is 30, we can
call 30 composite. A prime number is a number whose factors are
only 1 times the number, such as 3, 5, 7, 13, and 29.

### If 1 is neither a prime nor a composite no then what is it?

The number 1 is a unit - "unity" - it is neither
prime nor composite.
It is a matter of definition. It looks as if 1
should be a prime because 1 is only divisible by 1 and itself, but
a prime is defined to be a number with exactly two factors - 1 and
itself - but 1 has only one factor.
In addition, stated positively then, the number 1 is the first,
non-zero, natural number.
Number one has a unique role...

###### Asked in Algebra, Prime Numbers

### If 0 and 1 are not composite or prime numbers then what are they?

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...

There is no highest prime number. Given any set of prime
numbers, you can prove that there is at least one prime number that
is not in that set. Here's how.
First, recall that every natural number is either a prime
number, or is a composite number and thus the product of some
series of prime numbers.
Now, suppose you have a set of n prime numbers, P1 .. Pn.
Multiply them all together and add one. Call this number Q.
