Question

Number which is neither prime nor composite :
1. 2
2. 1
3. 4
4. 3

Answer 1

Correct Answer - Option 2 : 1

Given:

Some numbers = 2, 1, 4, 3

Concept:

Prime number = A number that can be divided exactly by itself and 1 or has exactly two divisor

Composite number = A with more than two factor

Calculation:

⇒ 2 = A prime number

⇒ 1 = Neither prime nor composite

⇒ 4 = A composite number

⇒ 3 = A prime number

∴ The required result will be 1.

 The number 1 is not a prime number since it has only one divisor (1)
