Program 8-  Write a shell script to find the GCD of two given numbers. 

Source Code

 # Function to find the GCD using the Euclidean algorithm

gcd() {

    dividend=$1

    divisor=$2

    while [ $divisor -ne 0 ]; do

        remainder=$((dividend % divisor))

        dividend=$divisor

        divisor=$remainder

    done

    echo "$dividend"

}

# Main program starts here

# Prompt the user to enter the first number

    echo "Enter the first number: "

    read num1

    # Prompt the user to enter the second number

    echo "Enter the second number: "

    read num2

   

# Find the GCD of the two numbers

result=$(gcd $num1 $num2)

echo "The GCD of $num1 and $num2 is: $result"

Sample Output:
