Hello EGmat,

Thanks for such a nice free video for prime numbers.
I really liked it.

I have a doubt regarding the last question tough.

The question is A and B are positive integers. Is A/B also an integer.
A all factors of B are also factors of A
B all prime factors of B are also factors of A

The answer you explained is A

I agree and got the concept of difference between prime factors and factors of a number.

But, shouldn't you say somewhere in question question explicitly that A> B to hold A to be true.
There is a possibility of it too.. If that's the case, answer should be E right?

In the question,

" The question is A and B are positive integers. Is A/B also an integer.
A all factors of B are also factors of A
B all prime factors of B are also factors of A"

A/B will be an integer only if A>=B. Thus it is not required to mention this separately in the question.

I could solve these questions but my timing was terrible (>5mins)

Should I expect such questions in the official exam?

I have solved a lot of questions (from OGs and from mocks as well) but I didnt encounter questions like these

TIA!

I haven't seen the video so don't know the questions discussed but judging by the last question in the comments above, they seem to be absolutely fair play. Most OG questions are about 600-650 level.
