Question

Find out a number which is neither prime nor composite.

Answer 1

Finding the number which is neither prime nor composite:

The prime number are the numbers which is having only $2$ factors i.e., one and the number itself. Ex- $2,3,5,7,11...$

The composite numbers are the numbers having more than two factors. Ex- $4,6,8,9...$

The number $1$ has only one factor which is itself. So, it is neither prime nor composite.

Hence, the number $1$ is neither prime nor composite.
