# What numbers are prime and composite?

A prime number is an integer greater than one which has no positive integral factors other than itself and one.

A composite number (or non-prime) is an integer greater than one which has positive integral factors other than itself and one. Alternate definition: A composite number (or non-prime) is an integer greater than one which has at least two prime factors.

The numbers 0 and 1 are neither prime nor composite, by definition.

60 = 1 x 2 x 2 x 3 x 5, so 60 is a composite number.

59 and 61 are prime numbers, because the only way to describe them as a product of positive integers is 59 = 1 x 59 and 61 = 1 x 61.

3599 is a composite number, because 3599 = 1 x 59 x 61.

Prime numbers are numbers that only 1 and the number itself can be divided into (e.g, 3: no other number can divide into it)

Composite numbers are numbers that more than 1 number besides itself and 1 can be divided into (e.g, 9: more than 1 number can divide into 9).

-------------------------------------------------------------------------------------------

A Prime number is a number that only has 2 factors, 1 and itself.

Example:11

A Composite Number has more than one factor besides 1 and itself.

Example:44

Note ALL even numbers (except 2) are composite.

A prime number is an integer which is not a product of any integers but itself and 1.

Example : 7 is prime, because it has no factors except 7 x 1

A composite number is an integer that is a product of smaller prime numbers.

These smaller integers can evenly divide the number and are called its factors.

Example : 55 is a composite number, because it can be created as the product of 5 x 11.
A prime number is a positive integer that has only two factors: one and itself.

A composite number is a positive integer that has more than two factors.
A prime number is a positive integer with two factors: one and the number itself.

A composite number is a positive integer with more than two factors.
A prime number is a whole number that only has two factors which are itself and one. A composite number has factors in addition to one and itself.

The numbers 0 and 1 are neither prime nor composite.

All even numbers are divisible by two and so all even numbers greater than two are composite numbers.

All numbers that end in five are divisible by five. Therefore all numbers that end with five and are greater than five are composite numbers.

The prime numbers between 2 and 100 are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89 and 97.

Prime or composite is an attribute of integers only; the numbers 0 and 1 are neither prime nor 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.

Prime numbers are integers (counting numbers) that cannot be divided evenly by any other integers other than 1 and themselves. Some numbers that are prime are: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, and 41. (The number 1 is not a prime number by definition.)

Composite numbers are integers that can be factored. Some examples are 4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 20, 21, 22, 24, 25, 26, 27, 28, 30, 32, 33, 34, 35, 36, 38, 39, 40 and onward.

If we look at all the integers, all the counting numbers, we'll see that they are either prime or composite numbers. And the set of all prime numbers and the set of all composite numbers (and the number 1) will be all the (positive) integers.

There are no such words as "frime" or "composive". Please check your spelling and re-submit a question that we can understand. It would be useful to develop the habit of checking your questions for correctness and completeness before posting them.

This refers to whole numbers. A prime number is a whole number, greater than 1, which has no smaller (whole) factors. The first prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, 23, ...A composite number is one that can be split into smaller factors. For example, 4 = 2x2, 6 = 2x3, 77 = 7x11, etc.

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.

When referring to positive integers, prime means having only two factors and composite means having more than two.

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.
