Solution

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.
