In today’s post, we are going to talk about the **factors of 15**. Because many students are searching on Google, about prime factorization of 15. Also, we will discuss what is prime factorization, so if you are new to this website, make sure to check other posts, I assure you that you will found our content really helpful.

So let’s first discuss what is prime factorization and how can you do it on your own?

## What Is Prime Factorization?

It is the decomposition of prime number into prime factors. A prime number is a number that has only two factors, i.e., 1 and number itself. A composite number can also be written in the form of products of prime and this is what we called as prime factorization.

**How to find prime factors?**

It’s very easy you can use LCM or repeated division for finding prime factors. Remember you need to express the number in prime form. For example, suppose you have 12, now we know that 2×6=12 but you can’t say 2 and 6 are prime factors, as you know that 6 is not a prime number. We need to express 6 in form of prime factors i.e., 6 = 2×3

Hence prime factorization of 12 = 2 x 2 x 3 = 2^{2} x 3
