It's Think Thursday here at the mentalfloss.com Brain Game. Good luck!

Use each of the digits 1 through 9 once, in any order, to create two numbers - the product of which must be as large as possible. (The digits are just digits in a number, not exponents or anything else, and no other operators may be added to the mix.)

For example, 98765 × 4321 = 426,763,565. (This product is about half the size of the largest one possible, in case that information helps.)

As explained above, what rendering
of the digits from 1 through 9 results
in the highest possible product?

Here is the SOLUTION.

THE SOLUTION:

87,531 × 9,642 = 843,973,902.
