Question

Define prime and composite numbers with examples

Answer 1

PRIME NUMBERS: Numbers having factors 1 and number itself are known as prime numbers. The prime number is the simplest of a number. Let us see few examples of prime numbers.

• PRIME NUMBERS: Numbers having factors 1 and number itself are known as prime numbers. The prime number is the simplest of a number. Let us see few examples of prime numbers.For example, let us take a number say 11. It can be written as 11 × 1 and 1 ×11.

Composite numbers are numbers which have at least one factor other than the number itself and 1. Let’s look at a few examples.

• Composite numbers are numbers which have at least one factor other than the number itself and 1. Let’s look at a few examples.Let us take a number say 4. It can be written as 4 × 1, 1 ×4 and 2× 2 So the factors of 4 are 1, 2 and 4. Therefore, we can say that 4 is a composite number.
• Composite numbers are numbers which have at least one factor other than the number itself and 1. Let’s look at a few examples.Let us take a number say 4. It can be written as 4 × 1, 1 ×4 and 2× 2 So the factors of 4 are 1, 2 and 4. Therefore, we can say that 4 is a composite number.Now, let us take a number say 6, can be written as 6 × 1, 1 ×6, 2× 3 and 3× 2. So, the factors of 6 are 1, 2, 3 and 6. Therefore, we can say that 6 is a composite number.

Answer 2

Step-by-step explanation:

PrimeNumbers

Every prime number have exactly 2 factors. Numbers having factors 1 and number itself are known as prime numbers. The prime number is the simplest of a number.

CompositeNumber

Composite numbers are numbers which have at least one factor other than the number itself and 1.
