1 is neither a prime nor a composite number because it has only one factor (itself (1)). The definition of a prime number is a number that has the factor of one and itself, so one is not prime. The definition of a composite number is a number that has more than 2 factors, so one is not composite. One is a special number.

A prime number is a natural number greater than one that can only be divided evenly by itself and 1. A composite number is the opposite of a prime number. By definition, every natural number greater than one is either prime or composite.

One is neither a prime nor a composite number.

A composite number is basically one that is NOT a prime - a composite number is a product of two or more primes.

If a number is "on[l]y divisible by one and [a] prime number", as required by the question, then that number is prime. Therefore it cannot be composite.

A number is prime when it only has one and itself as factors is prime. Therefore, to tell if a number is prime or composite simply find it's factors. If it has more than two factors than it is not a prime number, it is composite.

Composite A prime number is a number that has only two factors (itself and one) A composite number is a number that has more than two factors.

If it is a composite number, it is divisible by at least one prime number.

No, a composite number can't have more than one prime factorization.

Composite

The 'opposite' status of a number that is not prime is a composite number.Except for 0 and 1, all numbers that are not prime (i.e. they are multiples of other numbers) are called composite numbers.The opposite of a prime number would be a number that is not prime. Almost all numbers that are not prime are composite numbers. A prime number is a number that has exactly two factors. A composite number has more than two factors. However, composite numbers do not include all numbers that are not prime. The number 1 has only one factor, so it is neither prime nor composite - it is unity.

All natural numbers (counting numbers) greater than one are either prime or composite. If divisible by only one and the number itself, it is prime; if divisible by other natural numbers, then is composite. One is the only natural number that is neither prime nor composite.

It is a composite number.

a prime number is a number that you can plus by one

1 is not considered to be a prime or composite number because it has only one factor which is itself.

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.

Yes 19 is prime. Prime is when the number only has two factors. One and itself. A compostie number is a number that has more than two factors. The only number that is not prime or composite is 1. One is a special number. It is the only number that isn't prime or composite.

No composite numbers are prime. A composite number is a number that can be made by multiplying other numbers. A prime number is made only by one and itself. Therefore no number can be both prime and composite

To determine which number is a prime or composite number, your number must only have two factors, the number itself and one, if it more then two factors then it is a composite number.

A prime number is a natural number that has exactly two distinct natural number divisors: 1 and itself. A composite number is a positive integer which has a positive divisor other than one or itself.

There is no special name for it. It is simply neither prime nor composite.

The number 1 is neither a prime nor a composite number.

A composite number is the product of two or more prime numbers. A prime number has exactly two factors, 1 and the number itself; a composite number has at least one more factor than the two that a prime number has.

no. 1 is nither a prime number nor a composite number.

81 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.
