JavaScript modulo condition

[jaydel bujawe]

how can you say it in a decision using if in java script that you only do the condition if two variables can be divided but should be without remainders?

java script

What code is needed if i make a "while" loop in java script and inside it there's an "if" which makes decision. And the condition is i have to divide two variables. the one variable is asked from the user and the other variable is set to 2.So, the condition to continue the if is if the two variables is divided without remainders and the else portion is to add 1 to the variable that we set to 2.how can i do that in java script?

"modulo operator" is the appropriate keyword

what does your code look like (even if it does not yet work)?

java script

what does your code look like (even if it does not yet work)?

begin
		input N
		set F to 2
		while N > 1
			if N divides F without a remainder then
				output F
				set N to N / F
			else
				add 1 to F
			end if
		end while
end

this is how it looks like in pseudocode. i can't convert it to java script starting from the while loop. this is how my code looks like..

<script>
var userNum = prompt("Please supply an integer which is > (greater than) 1");
document.write("entered number is " + userNum);
var factor = 2;

while (userNum > 1) {
  if ((userNum/factor)== wholenumber){
  document.write(userNum + "<br /> is ");
}
 else {
 factor + 1;
 }

}

and this is how my code looks and its not working because i don't know how to program it to know that when they divide, it should not have a denominator.
