Brain Game: Zero Hour
By BY

I couldn't determine the original source of today's math puzzle chestnut; I've seen it in a few places, so suffice to say that it's several years old. It's still a great puzzle and a fun challenge. Good luck:
Group the digits 1-9 into a set of three 3-digit numbers, using each digit only once in a set. The second number should be exactly DOUBLE the first number; and the third number should be exactly TRIPLE the first number. There are three FOUR* possible sets of numbers that correctly solve this puzzle; can you find one (or all of them)?
* see in comments!
Here are the SOLUTIONS.
SOLUTIONS:
192...384...576
219...438...657
273...546...819
327...654...981
