What number multiplied equals 1280?

Answer 1

There are infinitely many possible answers.

Select ANY number, X that is less than sqrt(1280) = 35.777 (approx).

Let Y = 1280/X so that Y > X

Then XY = X*(1280/X) = 1280

And since Y > X, each X gives a different pair and then, because there are infinitely many options for X, there are infinitely many possible answers.

Some examples:

1 * 1280

10 * 128

12.8 * 100
