I want to change the rear fan on my hp omen obelisk but I don't know the size. My specific Hp Omen Obelisk is the 875-1009.

I should ask why? Just need to replace it, or much faster fan (more noise is likely).
Then tell you that the fan is a PWM 4 pin fan. The mounting bolt pattern is a particular fan size. Here is how to determine the fan size. When you answer that question, I can respond.
