i cant seem to figure out how to get the computer to know even / odd numbers using it for a prime factors. not looking for someone to do it for me just need a nudge in the right direction

create code that asks the user to supply an integer greater than 1 and then display all the prime numbers that multiply together to get the user’s number. If a number is a prime, its only factors are itself and one.

```

<body>
<script>
var integer;
var factor;
var fn;
integer= 1;
factor= prompt ("plz instert a number greater then 1");
fn= 2;
if (factor <= integer) {
alert ("invalid number");
} if (fn / integer) == 0 ){
alert ("even");
}
</script>
</body>
</html>
```
