The number 1 is neither composite nor prime.

Yes. All prime numbers and composite numbers are positive integers, or whole counting numbers. That leaves infinitely many numbers that are neither prime nor composite. If you intended to narrow the scope of your question to the whole counting numbers or to the positive integers, then there are NO such numbers that are neither. A counting number, however large, will be either prime or composite.

A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite.

0 is neither a prime or a composite number. It can not be divided by any number, so it would be difficult to classify it as prime or composite. 0 and 1 are the only numbers that are not prime and are not composite.

Yes, composite numbers have both prime and composite factors.

There is no such number. All numbers have a common factor of 1, which is neither prime nor composite. Any composite number can be reduced to its prime factors.

1 is neither a prime or composite number

Prime numbers have two factors. Composite numbers have more than two (but a finite number.)Zero and one don't fit either of these categories.

Prime factorization never includes a composite number. All numbers in prime factorization must be prime numbers.

A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite. yes, there are 8 digit prime numbers.

Depends on your definition of "numbers" - basically, every integer greater than one is either composite or prime. Therefore there are many numbers that are not composite or prime: 1, or 0, any negative number, any positive real non-integer, any complex number with imaginary part non-zero

The integers less than or equal to 1 and any numbers which are not integers.

It is prime. By the way, any integer greater than 1 is either prime or composite. "Neither" is not an option in such a case.

A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite.

A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite.

Please note that there are infinitely many prime numbers. An Internet search for "list of prime numbers" will quickly give you a list of prime numbers up to a certain point, for example here: http://en.wikipedia.org/wiki/List_of_prime_numbers Any integer greater than 1 that is not in the list of prime numbers is a composite number. (1 is considered neither a prime number, nor a composite number.)

Any number that isnot a prime,not a factor of the composite numbercannot appear in the prime factorisation of a composite number.

no theres not

Yes, 0 and 1 are neithe prime nor composite.

1 is the only natural number which is neither prime nor composite. So, 61 is either prime or composite. 61 is not divisible any number except 1 and itself so it is a prime number.

The number 23 is a prime number. It has only 1 and 23 as its factors.

There are not any numbers that are both prime and composite. A prime number has exactly two factors. A composite number has more than two factors.

120 is a composite number. 120 is a composite number. A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite. Any even number (except 2) is composite.

A prime number is any whole, rational number that is only divisible by itself, 1 or -1. A composite number is a whole, rational number that is divisible by the above, plus any other whole number available. 1 and 0 are neither prime, nor composite.
