come by so much money

[Oceanlike]

In a grammar exercise, this question sounds weird:

- How did Steve come by/come across/come over so much money since his pay is low.

I have never come across a phrasal verb of come + preposition in such a context.

I don't know what is the answer.

Thank you.

- How did Steve come by/come across/come over so much money since his pay is low.

That should end with a question mark. Where did you find it?
I would use "come to have" in that sentence.

Come by - get to have/become the owner of
Come across - find accidentally
Come over - go to/visit (or slang for ejaculate upon)

Police officer: How did you come by that diamond necklace?
John: I came across it in the park.
Police officer: Why were you in the park?
John: My girlfriend had asked me to come over and I always walk across the park to get to her place.

It's a grammar exercise that I was doing. Yes, it was my mistake for forgetting the question mark.

Thank you.
