In this post I am going to describe the PHP Program which tell us how to find LCM. LCM stands for Least common multiple . LCM is the smallest number that is a multiple of all the numbers
<?php
if(isset($_POST['submit'])){
$number= $_POST['number'];
$ar=(explode(" ",$number));
$no= count($ar);
$n=0;
$num=2;
$lcm=1;
while($n!=$no){
$flag=0;
$n=0;
for($i=0;$i<$no;$i++){
if($ar[$i]==1){
$n++;
}
if($ar[$i]%$num==0){
$ar[$i]=$ar[$i]/$num;
$flag=1;
}
}
if($flag==1){
$lcm= $lcm*$num;
}
else{
$num++;
}
}
echo "The LCM of all the Number is ".$lcm;
}
?>
