Sorry if this seems like a random question, because it is. I want to see the an Arceus with equal stats across the board with EVs. Thanks!

85/85/85/85/85/85

510 divided by 6 = 85

Maximum of EVs you can put on a Pokémon is 510 EVs. Now there are 6 stats.

510 : 6 = 85 EVs in each stat average.

It is actually 85/85/85/85/85/85
