A question just popped to my mind while reading GMAT Math book P.5
For a number to be considered as a prime, it has to have as a factors ( 1 and itself) but for example, 5 factors are ( 1 and 5, -1 and -5)
And how 1 (and -1) are divisors of every integer?
May please someone clarify?

By definition prima numbers MUST be positive, cannot be negative.
This is a question we are happy to address but a one second search on google would help you as well
