Introduction

Prime factorization is a fundamental concept in mathematics that involves expressing a number as a product of its prime factors. In this article, we will explore how to express the numbers 18 and 24 as products of their prime factors.

What are Prime Factors?

Before we dive into the prime factorization of 18 and 24, let's briefly discuss what prime factors are. Prime factors are the prime numbers that multiply together to give the original number. For example, the prime factorization of 6 is 2 x 3, because 2 and 3 are prime numbers that multiply together to give 6.

Prime Factorization of 18

To express 18 as a product of its prime factors, we need to find the prime numbers that multiply together to give 18. The prime factorization of 18 is:

18 = 2 x 3 x 3

In this expression, 2 and 3 are the prime factors of 18. We can see that 2 and 3 are multiplied together three times to give 18.

Prime Factorization of 24

To express 24 as a product of its prime factors, we need to find the prime numbers that multiply together to give 24. The prime factorization of 24 is:

24 = 2 x 2 x 2 x 3

In this expression, 2 and 3 are the prime factors of 24. We can see that 2 is multiplied together three times and 3 is multiplied once to give 24.

Why is Prime Factorization Important?

Prime factorization is an important concept in mathematics because it helps us understand the properties of numbers. By expressing a number as a product of its prime factors, we can gain insights into its divisibility, factors, and other mathematical properties.
