## README

# compute-lcm
基于[compute-lcm](https://www.npmjs.com/package/compute-lcm)原库1.1.2版本进行适配

## Install
```sh
ohpm install compute-lcm
```

## Usage

> Computes the [least common multiple](http://en.wikipedia.org/wiki/Least_common_multiple) (lcm).

__Note__: the lcm is also known as the __lowest common multiple__ or __smallest common multiple__ and finds common use in calculating the __lowest common denominator__ (lcd).

``` typescript
import lcm from 'compute-lcm';
```

#### lcm( a, b[, c,...,n] )

Computes the [least common multiple](http://en.wikipedia.org/wiki/Least_common_multiple) (lcm) of two or more `integers`.

``` javascript
let val = lcm( 21, 6 );
// returns 42

let val = lcm( 21, 6, 126 );
// returns 126
```


#### lcm( arr[, clbk] )

Computes the [least common multiple](http://en.wikipedia.org/wiki/Least_common_multiple) (lcm) of two or more `integers`.

``` javascript
let val = lcm( [21, 6] );
// returns 42

let val = lcm( [21, 6, 126] );
// returns 126
```

For object `arrays`, provide an accessor `function` for accessing `array` values.

``` javascript
const data = [
	['beep', 4],
	['boop', 8],
	['bap', 12],
	['baz', 16]
];

const getValue = (d: (string | number)[], i: number) => {
    return d[1];
};

let val = lcm( data, getValue );
// returns 48
```

## Notes

- If provided a single `integer` argument or an `array` with a length less than `2`, the function returns `null`.
