THE THREE GROUPS.

(Money Puzzles)
There appeared in "Nouvelles Annales de Mathematiques" the following
puzzle as a modification of one of my "Canterbury Puzzles." Arrange the
nine digits in three groups of two, three, and four digits, so that the
first two numbers when multiplied together make the third. Thus, 12 x
483 = 5,796. I now also propose to include the cases where there are

the possible solutions in both cases?
