Take a look at this, factor GNU tools available in Ubuntu.

#!/bin/bash
num=
if [ "$num" -ge 100 ]
then
factor="`factor $num`"
echo "Factor of number $num is $factor"
else
echo "Enter number is not a 3 digit number"
fi

Or you can strictly limit it to only accept 3 digits.

#!/bin/bash
num=
if [ "$num" -ge 100 ] && [ "$num" -lt 1000 ]
then
factor="`factor $num`"
echo "Factor of number $num is $factor"
else
echo "Enter number is not a 3 digit number"
fi
