Question

The least two digit composite number is

• A. $11$
• B. $12$
• C. $10$
• D. $16$

Answer 1

The correct option is C $10$

We know that-If a number has more than $2$ factors then it is a composite number.

$11$ is a prime number $\because$ it has only $2$ factors

$12$ is a composite number $\because$ it has more than $2$ factors

$10$ is a composite number $\because$ it has more than $2$ factors

$16$ is a composite number $\because$ it has more than $2$ factors

$\therefore 10,12,16$ are composite numbers.

The least composite number is $10$
