Hi mohit,

1) take the number WS-CTR1 from user /JCl
2) Now get the square root of the number using some math function & move it to WS-CTR2.
3)Now check whether WS-CTR1 is divisible by any number between 2 & WS-CTR2
4)If it is divisible then it is not a prime number otherwise it 's prime number.

Please let me know if u need any further explanation
