In Linux, there is a command-line utility called a very useful factor for those users who work with a prime number.

The product of any prime number generates the original number referred to as **Factor.**

Factor command in Linux supports us to print prime Factor. For this, we need to enter the number as a parameter with the factor command. If you donâ€™t give any argument, it will read through standard input.

**Syntax**

**Non-prime number**

**Example 1:
**First, let’s get the prime Factor, a non-prime number. In my case, I want to find the prime factor of 10 that is a non-prime number.

The number 10 is a product of the prime factors 2 and 5.

**Example 2:**

The prime factor of 250 is 2 2 5 5.

**Multiple prime factors**

Pass multiple numbers as an argument to do prime Factor simultaneously.

**Prime number**

So, let’s do the factorization of 77. The number 77 is the product of combining prime numbers.

**The prime number itself **

Factorization of 17 would be 17 itself because 17 is a prime number and can’t divide on any other number.

**Conclusion**

The factor command returns a number’s prime factors. It prints the prime factors for each integer NUMBER. If you don’t pass any argument, it will read from standard input. We did factorization of a particular prime number in this tutorial.
