Help Help Help in recursion

Hello every body. I am trying to find the factorial using the following code. But it is giving the syntax error. I tried very much but in vain. Thanks in advance for helping me

factorial()
{
if [ $1 -gt 1 ]
then
y=`expr $1 - 1`
x=$(( $1 \* factorial $y ))
return $x
else
return 1
fi
}
echo -n "Enter number = "; read n
factorial $n
