Incorrect Percentage for Memory Utilization.

I am running the command
Code:
/usr/bin/free -b | awk '/Mem:|cache:/ {print $2,$3}' | sed 'N;s/\n/ /' | awk '{print ($4*100)/$1}'

to find out Memory utilization,


it is showing 205%, please suggest me what changes are required, below is output of free -b command.

Code:
[test@linuxtest ~]$ free -b
             total       used       free     shared    buffers     cached
Mem:    1353938452 1348477050  546140160 3532815564  163950592 1319080386
-/+ buffers/cache: 2775715840 1326181294
Swap:   1677721190   57024512 1672018739
