<html>

    <script language="JavaScript">
    function multiple5(){
    var num1, num2, num3=5, num4="", mult=5, result;
    
    num1=parseInt(prompt("Introduce un número:",""));
    
    if(num1>>0){
    num2=num1;
    num1=1;
        for (num1=num1;num2>=num1;num1++){
            result=num1%mult;
            if(result==0){
                num3=num3+mult;
                num4=num3;
                //text();
            }
        }
            alert(num4+" ");
    }else{
        alert("Lo siento pero el número introducido no es mayor a 0");
    }
    
}

    </script>
    
    <form name="formulario" method="post" action="">
        <input type="button" onClick="multiple5()" value="Multiples de 5">
    </form>
</html>

If there is an easier way to simplify it, please tell me so it would help me a lot, I’ve been doing this for more than 3 hours, and I can’t figure out how the hell to fix it, the output is just all the multiples added giving 30 if you put 25

>Solution :

function showMultiplesOf5() {
  var num = parseInt(prompt("Enter a number:"));
  if (num > 0) {
    var multiples = "";
    for (var i = 5; i <= num; i += 5) {
      multiples += i + " ";
    }
    alert("Multiples of 5: " + multiples);
  } else {
    alert("Sorry, the number entered is not greater than 0.");
  }
}
