They cannot be integers or whole numbers; but they can be numbers with decimals. There are many possibilities; if the numbers are the same, then that is the square root of 10000000 which is 3162.277666...repeating. Those same numbers multiplied together = 10000000. If numbers are different, there are other combinations, all involving decimals
Those numbers are called factors. A pair of those is called a factor pair.
The numbers are: -27+6*sq rt of 14 and -27-6*sq rt of 14
