Examples

Here are some examples of how to use the utility methods from the package:

$3

To gain the TypeScript typings (for intellisense / autocomplete) while using CommonJS imports with require(), use the following approach:

`js
const divisor = require('divisor');
`

$3

To gain the TypeScript typings (for intellisense / autocomplete) while using ES Module imports with import, use the following approach:

`js
import divisor from 'divisor';
`

$3

To get the divisors of a number:

`js
const divisors = divisor.getDivisors(20);
// outputs => [ 1, 20, 2, 10, 4, 5 ]
`

To get the sorted divisors of a number:

`js
const sortedDivisors = divisor.getDivisors(20, { sort: 'asc' });
// outputs => [ 1, 2, 4, 5, 10, 20 ]
`

$3

`ts
{
sort?: string | undefined; // optional - supports 'asc' | 'desc'
onlyProperDivisors?: boolean; // optional
}
`

$3

To get all common divisors:

`js
const commonDivisors = divisor.getCommonDivisors(20, 100);
// outputs => [ 1, 20, 2, 10, 4, 5 ]
const sortedCommonDivisors = divisor.getCommonDivisors(20, 100, {
sort: 'desc', // supports 'asc' | 'desc'
});
// [ 20, 10, 5, 4, 2, 1 ]
`

To get the greatest common divisor - gcd:

`js
const gcd = divisor.greatestCommonDivisor(20, 100);
// outputs => 20
`

To get the least common multiple - lcm:

`js
const lcm = divisor.leastCommonMultiple(11, 67);
// outputs => 737
`
