What numbers equal 200 in multiplication?

Answer 1

There are infinitely many possible answers.

Let A be any number in the interval (0, sqrt(200)] = (0, 14.142] approx.

and let B = 200/A so that A <= B

Then A*B = A*200/A = 200.

Since A was an arbitrary real number in the given range, there are infinitely many possible values for A and so infinitely many pairs.

Next, it is possible, similarly, to generate triplets, quartets, ... n-tuples, such that they multiply to 200.
