In this case, the each team plays against 5 teams within their own division five times, which gives you a cumulative total of 175 games. (7*5*5 = 175)
Each team then plays against 1 team within their own division four times, which gives you a cumulative total of 175 games. (7*1*4 = 28)
175+28 = 203

I think you are missing the boat...
In each seventeam division, a pair of teams must play the four games. In a division with an odd number of teams, it may look mathematically possible, but it is impossible:
Los Angeles and Vancouver:
Plays all teams in Pacific five times, except each other only four
Anaheim and Calgary:
Plays all teams in Pacific five times, except each other only four
Phoenix and Edmonton:
Plays all teams in Pacific five times, except each other only four
What about San Jose?
