Question

The smallest composite number is ______

• A. $2$
• B. $4$
• C. $1$
• D. None of these

Answer 1

Answer: (B)

$4$

By definition of a composite number, It is a number that has other divisors besides $1$ and the number itself. here,'$1$ ' is not a composite number because its divisor is one. and '2' is also not a composite number because it has only two divisors $1$ and the number 2 itself but 4 is different. Its divisors are 1,2 and 4. So, this number satisfies the criterion of a composite number as stated above, Since besides $1$, $2$ is also a divisor of $4$. So the answer is $4$
