3 and 1, as well as -3 and -1, are the only numbers that, when multiplied, produce a product of 3.
Yes. Natural numbers, or counting numbers, cannot produce non-natural numbers, or complex numbers, through methods of multiplication or addition. However 5 divided by 3 creates the complex number 1.666666.... So division of two naturals can produce a complex. Also 6 minus 10 creates -4 which is not a natural number.
11# - 1 = 2309 and 11# + 1 = 2311, both of which are prime.
p7# - 1 = 510509 and p7# + 1 = 510511, neither of which is prime.

Two.
Numbers are infinitely dense. Between any two rational or real numbers, no matter how close, there are infinitely many numbers.
Yes: Multiplying any two counting numbers will produce a counting number.
The answer is the quantity of the two numbers
There's no formula. If a number has more than two factors, it's composite.
