# factor

Returns the prime factorization of `X`. If two outputs are requested,
returns the unique primes of `X`.

## Syntax

factor(X)

## Inputs

`X`- Integer to be factored.

## Outputs

- R, n
- Prime factors of
`X`.

## Examples

Simple factor example:

`factor(14)`

`R = [ 2 7 ]`

Multiple output factor example:

```
[a,b]=factor(12)
disp(a)
disp(b)
```

```
a = [ 2 3 ]
b = [ 2 1 ]
```
