WRONG!
They are coprime, not prime.
GCF(8, 9) is 1 but neither 8 nor 9 is a prime.
Mathematicians call them "factor pairs."
There are mathematical concepts that mathematicians call "imaginary numbers" these are a multiple of the square root of minus 1. Infinity is not a real number either.

Numbers whose factors only include one and themselves are called Prime numbers.
That number is called "i", the imaginary unit. The name "imaginary" is for historical reasons; these numbers have many practical applications, for example in electricity.
There are infinitely many pairs. 1) Pick a value for one of the numbers - call this A 2) The second number, B = 0.47 - A

A regular octagon
A polynomial.
There is no proof that such pairs exist.
Most mathematicians would call that a 1000-gon. If you want to show off, call it a "chiliagon."
Numbers that are reciprocals of each other are called "reciprocal pairs." For example, if you have a number ( x ), its reciprocal is ( \frac{1}{x} ). When two numbers are reciprocals, their product equals 1.
