The largest, greatest, highest or biggest number of . .

I'm not a native speaker, and my teacher taught me to use "the biggest number of . . ." when comparing amounts of some things, but I've checked it in google which seems like "the largest, the greatest, the highest, and even the most number of. . ." are actually used more often.

1. Which do we usually use for comparing numbers or amounts of some things?

Let's say, if there were 3 cities.

• 1,000 people live in city A.
• 2,000 people live in city B.
• 3,000 people live in city C.

2. How do you compare those numbers of people?

• You will need to turn to a corpus to know for sure what people actually do or do not prefer. See e.g. this related question on greater/higher/heavier/bigger/larger/stronger weight Commented Oct 25, 2018 at 17:59
• Thanks @RegDwigнt, your comment is very helpful :) Commented Oct 25, 2018 at 18:17
• Make sure to actually check those corpora for your specific collocation (the first 15 searches are free even if you don't register.) The picture might look very different for sizes as opposed to weights as opposed to heights and so on. I would do that myself and post a detailed answer, but I'm kind of in the middle of something right now. Commented Oct 25, 2018 at 18:26
