Please help me to write a shell script to find the GCD (Greatest common Divisor) of 3 numbers.
Thanks in advance.

No, we suggest, you do it.My suggestion is you look to see if your shell supports functions, which you can call in the manner I've described.

Project work
I got a program to find the GCD of 2 numbers. But i need the program to find the GCD of three numbers.
Program to find the GCD of 2 numbers is as follows
echo "Enter first number"
read n1
echo "Enter the second number"
read n2
gcd=0
if test $n1 -gt $n2
then
i=1
while test $i -le $n1
do
a=`expr $n1 % $i`
b=`expr $n2 % $i`
if test $a -eq 0 -a $b -eq 0
then
if test $gcd -lt $i
then
gcd=$i
fi
fi
i=`expr $i + 1`
done
fi
if test $n2 -gt $n1
then
i=1
while test $i -le $n2
do
a=`expr $n1 % $i`
b=`expr $n2 % $i`
if test $a -eq 0 -a $b -eq 0
then
if test $gcd -lt $i
then
gcd=$i
fi
fi
i=`expr $i + 1`
done
fi
echo GCD of $n1 and $n2 = $gcd
So please write a program to find the GCD of 3 numbers.

I tried but I am unable to write the program.
So please write the whole program for me.
Please.
So did you do ANY research on how to write a function in shell?
Did you try a few examples to see how it might work for you?
