Write a shell program to find greatest common divisor GCD of the given three number?

Answer 1

Shell program for greatest common division (G.C.D.) Of the given three number:-

echo "Enter Number 1:-"

read a

echo "Enter Number 2:-"

read b

echo "Enter Number 3:-"

read c

gcd=1

if [ $a -ge $b ]

then

s=$a

else

s=$b

fi

if [ $s -ge $c ]

then

t=$s

else

t=$c

fi

i=1

while [ $i -le $t ]

do

d=`expr $a % $i`

e=`expr $b % $i`

f=`expr $c % $i`

if [ $d -eq 0 -a $e -eq 0 -a $f -eq 0 ]

then

gcd=$i

fi

i=`expr $i + 1`

done

echo "The GCD of $a,$b and $c is $gcd"
