**Prime Numbers**

Prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself

In other words, we can say prime numbers don’t have any factor other than 1 and itself.

**Composite Numbers**

Composite numbers are divisible by one or more numbers other than 1 and itself.

In other words, we can say that numbers having more than two factors are composite numbers.

**Examples of Prime Numbers**

**QUESTION**

Is 2 is a Prime number?

**EXPLANATION**

Prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself

In other words, we can say prime numbers don’t have any factor other than 1 and itself.

Factors of 2 are

2 ÷ 1

2 is not divisible by any other number, other than 1 and itself

therefore, 2 is Prime number.

**QUESTION**

Is 6 is a Prime number?

**EXPLANATION**

Prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself

In other words, we can say prime numbers don’t have any factor other than 1 and itself.

Factors of 6 are

6 ÷ 1 = 6

6 ÷ 2 = 3

6 ÷ 3 = 2

6 ÷ 6 = 1

6 is divisible by 1 , 2 , 3 and 6

therefore, 6 is not a Prime number.

**Examples of Composite Numbers**

**QUESTION**

Is 4 is a Composite number?

**EXPLANATION**

Composite numbers are divisible by one or more numbers other than 1 and itself.

In other words, we can say that numbers having more than two factors are composite numbers.

Factors of 4 are

4 ÷ 1 = 4

4 ÷ 2 = 2

Factors of 4 are 1 , 4 and 2

Therefore, 4 has more than two factors.

Hence, 4 is a Composite number.

**QUESTION**

Is 2 is a Composite number?

**EXPLANATION**

Composite numbers are divisible by one or more numbers other than 1 and itself.

In other words, we can say that numbers having more than two factors are composite numbers.

Factors of 2 are

2 ÷ 1 = 2

Factors of 2 are 1 and 2

Therefore, 2 does not have more than two factors.

Hence, 2 is not a Composite number.
