Plural of "two"

[Dawood Usmani]

Hi teachers!
What's the plural of "two", "three" and "four" etc. when they are used as nouns? Should I simply add ans "s" to them or apostrophe + "s"?
Best regards!

You didn't get me, dear. I want to turn the word "two" into plural. Is it "twos" or "two's" as in " Four two's make eight." Is it right?
Regards!

Yes. The animals went on board the ark in twos.
"Say, why is everything, either at sixes or at sevens." (G&S-Pinafore)

Except, of course:
two's company, three's a crowd :used to indicate that two people, esp. lovers, should be left alone together.

So my sentence should be "Four twos make eight." Am I right?
Looking forward to the answer...
