Question

What is the HCF of smallest prime number and the smallest composite number?

Answer 1

Find the HCF of the smallest prime number and the smallest composite number.

A prime number is a number that has only two factors that are $1$ and the number itself.

A composite number is a number that also has factors other than $1$ and the number itself.

HCF of two or more numbers is the greatest number than can divide the numbers exactly.

The smallest prime number is $2$.

The smallest composite number is $4$.

Factors of $2$ are $1,2$.

Factors of $4$ are $1,2,4$.

HCF of numbers $2,4$ is $2$.

Hence, the HCF of the smallest prime number and the smallest composite number is $2$.
