## Overview

The {gcd} package offers two functions:

- `gcd()`: greatest common divisor of two numbers.

- `lcm()`: least common multiple of two numbers.

The **main purpose** of this repo is to show how to **build a simple R package**:

1. Put all functions into one or more R scripts in folder "R"

2. Document them with Roxygen

3. Go through script "packaging.R"

To test it yourself:

1. Clone repo

2. Delete everything except "R/gcd" and script "packaging.R"

3. Go through script "packaging.R" 

## Installation

You can install the development version of gcd from [GitHub](https://github.com/) with:

``` r

# install.packages("devtools")

devtools::install_github("mayer79/gcd")

```

## Usage

``` r

library(gcd)

a <- 123

b <- 10947

gcd(a, b)  # 123

lcm(a, b)  # 10947

```
