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

Prime numbers are the numbers that have only two factors, that are, 1 and the number itself.

## Answer: The HCF of smallest composite number and smallest prime number is 2.

Composite numbers can be defined as natural numbers that have more than two factors.

**Explanation:**

The smallest prime number is 2.

The smallest composite number is 4.

To find the HCF of 2 and 4 let's write their prime factorization

2 = 2

4 = 2 × 2

HCF(2, 4) = 2
