Program to find the LCM of a number in PHP with form.

In this example, programmer stores the values in the variables. However, if you interested to see the program about taking values in the form, please see example 2.

<html>
<body>
<form method="POST"> 
Enter  First No. <input type="text" name="num1">
Enter Second NO.<input type="text" name="num2"><br><br> 
Result: <input type="submit" name="Ok">
</form>
</body>
</html>
<?php 
if (isset($_POST['Ok'])) {
  $num1=$_POST['num1'];
  $num2=$_POST['num2'];
  $max=($num1>$num2) ? $num1 : $num2;
    while(1)
    {
      if($max%$num1==0 && $max%$num2==0)
        {
          echo "LCM of " .$num1. " and " .$num2. " is: ".$max;
          break;
        }
    $max=$max+1;
    }
    }
     //echo '$max';

?>

<html>

<body>

Enter First No. <input type="text" name="num1">

Enter Second NO.<input type="text" name="num2"><br><br>

Result: <input type="submit" name="Ok">

</form>

</body>

</html>

<?php

if (isset($_POST['Ok'])) {

$num1=$_POST['num1'];

$num2=$_POST['num2'];

$max=($num1>$num2) ? $num1 : $num2;

while(1)

{

if($max%$num1==0 && $max%$num2==0)

{

echo "LCM of " .$num1. " and " .$num2. " is: ".$max;

break;

}

$max=$max+1;

}

//echo '$max';

Program to find the LCM of a number

In this example, we will take the inputs from the user and store them in variables.

<?php 
  $num1=3;
  $num2=4;
  $max=($num1>$num2) ? $num1 : $num2;
    while(1)
    {
      if($max%$num1==0 && $max%$num2==0)
        {
          echo "LCM of " .$num1. " and " .$num2. " is: ".$max;
          break;
        }
    $max=$max+1;
    }
?>

<?php

$num1=3;

$num2=4;

$max=($num1>$num2) ? $num1 : $num2;

while(1)

{

if($max%$num1==0 && $max%$num2==0)

{

echo "LCM of " .$num1. " and " .$num2. " is: ".$max;

break;

}

$max=$max+1;

}

Program to find the LCM of a number in PHP with a database.

In this example, we will take the inputs from the user and temporarily store them in variables and then finally stores them permanently in the database.

<html>
<body>
<form method="POST"> 
Enter  First No. <input type="text" name="num1">
Enter Second NO.<input type="text" name="num2"><br><br> 
Result: <input type="submit" name="Ok">
<br><br>
</form>
</body>
</html>
<?php 
$conn=mysqli_connect('localhost','root','','lcm');
if (mysqli_connect_error())
  {
  echo "Failed to connect to MySQL: " . mysqli_connect_error();
  }
if (isset($_POST['Ok'])) {
  $num1=$_POST['num1'];
  $num2=$_POST['num2'];
  $max=($num1>$num2) ? $num1 : $num2;
    while(1)
    {
      if($max%$num1==0 && $max%$num2==0)
        {
          echo "<input value=$max name=max><br>";
          break;
        }
    $max=$max+1;
   
    }
     mysqli_query($conn,"INSERT INTO lcm (First,Second,Result) 
VALUES ('$num1','$num2',$max)");
    mysqli_close($conn);
}
?>

<html>

<body>

Enter First No. <input type="text" name="num1">

Enter Second NO.<input type="text" name="num2"><br><br>

Result: <input type="submit" name="Ok">

</form>

</body>

</html>

<?php

$conn=mysqli_connect('localhost','root','','lcm');

if (mysqli_connect_error())

{

echo "Failed to connect to MySQL: " . mysqli_connect_error();

}

if (isset($_POST['Ok'])) {

$num1=$_POST['num1'];

$num2=$_POST['num2'];

$max=($num1>$num2) ? $num1 : $num2;

while(1)

{

if($max%$num1==0 && $max%$num2==0)

{

echo "<input value=$max name=max><br>";

break;

}

$max=$max+1;

}

mysqli_query($conn,"INSERT INTO lcm (First,Second,Result)

VALUES ('$num1','$num2',$max)");

mysqli_close($conn);

}
