# Find the LCM of the smallest composite number and the smallest prime number.

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

## Answer: The LCM of the smallest composite number and the smallest prime number is 4.

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 LCM of 2 and 4 let's do their prime factorization.

2 = 2

4 = 2 × 2

LCM(2, 4) = 2 × 2 = 4
