## What is `sympy` library?

At its core, **`sympy`** is a library used for symbolic mathematics. 

We use `pip` to install `sympy`. Refer to the following command:

```
pip install sympy
```

## The `primefactors` method

The **`primefactors` method** is used to return a sorted list of prime factors of a given number.

> **Note:** Prime factors are prime numbers that completely divide the given number to get zero as the remainder.

# 
## Syntax


```python
sympy.primefactors(n)
```

## Parameters

- **`n`**: This is the number for which prime factors need to be obtained.

## Return value

The method returns the prime factors of the given number.


## Code example

import sympy

n = 100

print("The prime factors of %s is %s" % (n, sympy.primefactors(n)))

python39

# 
## Code explanation

- Line 1: We import the `sympy` package.
- Line 3: We define `n`.
- Line 5: We use the `sympy.primefactors()` method to obtain the prime factors of `n`.
