Prime Numbers and **CompositeNumbers**. **APrime** Number is: a whole number **that** cannot be made by multiplying other whole numbers.

A positive whole number **that** is not **prime** is either unity (1) **orcomposite**. A **compositenumber** has smaller **prime** numbers as its factors; for example, **6** = 2 x 3.

A number **that** is not **aprime** number is called a **compositenumber** because it can be made by multiplying prime numbers together.

1 is neither **aprime** nor a **compositenumber**. Any even number other than two will be not be **aprime** number.

**Is6aprime** number or a **compositenumber**? Calculate prime factorization of 6 and list smaller and larger prime numbers than 6.

**Six** is a **compositenumber** because it can be divided by many numbers.

The **number** 1 is the only counting **numberthat** isn’t **primeorcomposite**, because its only factor is 1. The first **six** prime **numbers** are 2, 3, 5, 7, 11, and 13. When testing to see whether a **number** is **primeorcomposite**, perform divisibility tests in the following order (from easiest to hardest): 2, 5, 3...

**Compositenumbers** are positive integers **that** are exactly divisible, i.e., a zero remainder, by other positive integers besides just itself and 1, for example, **6** is a **compositenumber** because it is exactly divisible by not only itself and 1, but also by 2 and 3: **6**/**6** = 1, **6**/1 = **6**, **6**/3 = 2, and **6**/2 = 3. Another...

Example **6**: Is the number 31 **primeorcomposite**? Explain your answer using full sentences.

**Aprime** number is a whole number **that** only has two factors which are itself and one.

Is 93 **primeorcomposite**? Here you can find **a** '**Prime** Factorization Calculator' as well as a all the primes to 93.

Composites can be written as the multiplication of at least two other factors, where the two factors are not **that** number. For example, 2*3 = **6** means **6** is composite because you can write it out as a product of two other factors.

A **CompositeNumber** can be divided evenly by numbers other than 1 or itself. Example: **is6aPrime** Number **orCompositeNumber**?

Is the number one **aprimeor** a **compositenumber**? Why? (Please put your answer in a form **that** a **sixth** grader can understand.)

learn about which are prime, which is **composite**, remember **anprimenumber** is a integer **that** has no integral factors but itself and 1. A compisote **number** is an

No, **6** is not **aprime** number. Reason : Because it has more than two factors. Being **aprime** number, it must divisible by 1 and itself only.

Prime Number: A number **that** is divisible only by itself and 1 (e.g. 2, 3, 5, 7, 11). **CompositeNumber**: A number **that** can be formed by multiplying together two

**Number** Can be Evenly **Prime**, **or** Divided By **Composite**?
