Factors

---

Input a number and the script will give you all the factors of the number. Great for certain algebraic functions.

In Action

Code

The javascript to obtain the resalts is fairly simple.

function compute() {
	var i;
	var b = '';
	
	// Gather input
	var num = document.getElementById('input').value;
	
	// Cycle through found factors
	for (i = 0; i < num/2; i++) {
		// Do the math
		if(num % i == 0) {
			if (num/i < i) {
				break;
			}
			else {
				b += i + " : " + num/i + "<br>";
			}
		}
	}
	// Display results
	document.getElementById('blocks').innerHTML = b;
}

I wrote this script a long time ago and forgot what some of the math section does :P. I'll try to get more comments in there sometime.
