What times what equals -315?

Answer 1

Oh, what a happy little math problem we have here! To find two numbers that multiply to -315, we can think about factors. -315 can be written as -1 * 3 * 3 * 5 * 7. So, one possible pair of numbers could be -45 and 7, as -45 * 7 equals -315. Remember, there are different combinations that could work here, so feel free to explore and find the one that fits just right for you!

Answer 2

There are infinitely many possible answers.

Let x be any positive number and let y = -315/x. Then xy = -315.

So x = 1 gives y = -315

x = 0.5 gives y = -630

x = 100 gives y = -3.15

x = sqrt(5) gives y = -63sqrt(5)
