Step-by-step explanation:
Prime factorization says that, if a number is prime then the only way it can be factored is, 1 times the number itself.
But if the number is composite, it can be expressed as a product of prime factors. This method is called prime factorization.
For example: 12 is a composite number, it can be written in the form of prime factorization as,
![12 = 2 * 2 * 3](https://img.qammunity.org/2019/formulas/mathematics/middle-school/9lz4l54fiul67e0v8m0j507qnglel1ig6x.png)
Here we can see that 12 is expressed as the product of primes only. This is called prime factorization.
