EQ6 gear ratios

I'm perplexed by the mysteries of the EQ6 motors and gears.
I'm attempting to replace the motors in my EQ6 in order to deal with some erratic behaviour in one of the original motors.
When I started to transfer the motor gear and transfer gear from the old motors to the new, I found that the transfer gear on one motor had 36 teeth while that on the other had 32. The motor gear on each had 12 teeth.
I remember seeing in another thread a comment by Bojan that the number of teeth in the intermediate gear didn't matter. What mattered was the number of teeth in the motor gear and on the shaft of the worm.
Is that right? I am mathematically challenged I'm afraid, so getting my head around this is proving to be very difficult. I am hoping someone can help me understand how you get to a gear ratio of 705:1 for the standard EQ6 assuming a 200 step motor and 64 microsteps - or is it 32?
