<script type="text/javascript">

var inum, icount=2;

var irem;

inum = prompt("Enter a number.");

if(inum==1)

{

alert("The no. is not prime");

document.write("The no. is not prime");

exit(0);

}

if(inum==2)

{

alert("The no. is prime");

document.write("The no. is prime");

exit(0);

}

do

{

irem=inum%icount;

if(irem==0)

{

alert("The no. is not prime");

document.write("the given no is not prime");

exit(0);

}

icount++;

}

while(icount<=(inum/2));

alert("The no. is prime");

document.write("the given number is prime");
