Replace the *'s with single digits to make this multiplication work.


. . * * *
. . . * *
---------
. * * * *
* * * *

---------
* * * * *


I know, I know, usually you get one or two numbers filled in as a clue.
But given that each * represents a prime digit, 2,3 5 or 7, you probably don't need further help.

Formatting tip: use Courier new font and alternate spaces and white-colored dots for multiple spacing.
