Trouble thinking of a term or colloquialism for "much much more"

There is a saying that is on the tip of my tongue that basically means "immeasurably more than". I think it's related to "factor" but I just cannot place it. I also feel like it's commonly used in a technically incorrect way but I can't be sure.

Example Sentence:

The new process is _______________ simpler than the previous one.

I'm almost positive it's math related.

Solution 1:

The "more" aspect is already included in the word choice "simpler" of your example sentence. You might consider "exponentially", "immeasurably", or "infinitely" to fill in the blank. Each of these are math related words commonly intended to mean "vastly". In fact, you could use that one too.

The new process is vastly simpler than the previous one.
