can we consider negative prime numbers in this case?

For? The question says that a and b are positive.

yeah not for a and b, its not mentioned about prime numbers x and y

so if we consider -ve prime numbers for x and y

Thanks for the input, but I’m not sure how Fact 6 relates to my question,

My question was, “as it’s only mentioned a and b are positive integers, x and y are distinct prime numbers, can we consider negative prime numbers?”

Thank you so much!!

I feel so dumb right now!!
