# Definition (Primorial Of a Number)

*Is similar to factorial of a number*, **_In primorial_**, not all the natural numbers get multiplied, **_only prime numbers are multiplied to calculate the primorial of a number_**. It's denoted with **_P_****_#_** and it is the product of the first n prime numbers.
___ 

# Task

**_Given_** *a number N* , **_calculate its primorial_**. ![!alt](https://i.imgur.com/mdX8dJP.png)  ![!alt](https://i.imgur.com/mdX8dJP.png)  
___

# Notes

* **_Only positive_** numbers *will be passed (N > 0)* .
___

# Input >> Output Examples:

``` cpp
1- numPrimorial (3) ==> return (30)
```

## **_Explanation_**:

**_Since_** *the passed number is (3)* ,**_Then_** **_the primorial_** *should obtained by multiplying*  ```2 * 3 * 5 = 30 .```

### Mathematically written as , **_P_**3**_#_** = 30 .
___ 

## **_Explanation_**:

**_Since_** *the passed number is (5)* ,**_Then_** **_the primorial_** *should obtained by multiplying*  ``` 2 * 3 * 5 * 7 * 11 = 2310 .```

### Mathematically written as , **_P_**5**_#_** = 2310 .
___

## **_Explanation_**: 

**_Since_** *the passed number is (6)* ,**_Then_** **_the primorial_** *should obtained by multiplying*  ``` 2 * 3 * 5 * 7 * 11 * 13 = 30030 .```

### Mathematically written as , **_P_**6**_#_** = 30030 .
