Is every number either prime or composite?
No. It IS true that every whole number is either prime or composite. But there are numbers that are not whole numbers, such as 2.5, which are neither prime nor composite.
If a number is not a prime number what is it?
A positive whole number that is not prime is either unity (1) or composite. A composite number has smaller prime numbers as its factors; for example, 6 = 2 x 3.
Which is true about 143 It is a prime number It is a composite number It is a whole number that is neither prime nor composite or It is not a whole number?
We know that 143 is a whole number and that it has to be either prime or composite because all whole numbers other than 0 and 1 are one or the other. So, in order to determine if it is prime or composite, we need to know if any numbers besides 1 and 143 are factors. 1, 11, 13, and 143 are factors so 143 is a composite number.

Is 2.25 a prime or composite number?

Is 392 a prime or composite number?

What is 39 composite or prime number?
39 is composite... --------------------- A prime number is a whole number greater than 1, whose only two whole-number factors are 1 and itself.
Are there any number that are neither prime nor composite?
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.
Is the number 4 prime or composite?
Composite. All whole numbers ending in four are composite.
Is 910 prime or composite number?
Composite. All whole numbers ending in zero are composite.
Why is 41 a composite number?
It isn't. A composite number is any whole number that isn't prime, 1, or 0. A prime number is a number that can only be divided by itself or 1 to get a whole number. There is no whole number that you can divide 41 by to get another whole number (besides 1 and 41). Therefore, it is a prime number.
