You can do somthing like that :
Code:
c0=100
c1=12
c2=777
c3=1

clow=$c0
chigh=$c0

(( $c1 < $clow )) && clow=$c1
(( $c2 < $clow )) && clow=$c2
(( $c3 < $clow )) && clow=$c3

(( $c1 > $chigh )) && chigh=$c1
(( $c2 > $chigh )) && chigh=$c2
(( $c3 > $chigh )) && chigh=$c3

echo "Low : $clow"
echo "High: $chigh"

Output
Code:
Low : 1
High: 777
