From Lilith's Page:

"--It is revealed that she (Lilith) possesses a little more than 1/4 of Ophis' powers. This happened because Ophis sent most of her power to another space in the form of snakes while being caught by Samael  which she later retrieved.--"

From Ophis' Page:

"--According to Ddraig, her true abilities are stronger than the two Heavenly Dragons at their prime combined. So much so that when her powers were reduced to a level twice as powerful as the Heavenly Dragons, she felt "weak."--"

So this basically means that Ophis, at less than 1/4 of her full power, is more than twice as strong as the Heavenly Dragons in their prime.

Try to calculate the power coefficient against the Four Satans yourselves.
