Calculating Pandigital Numbers

[micseydel]

I'm searching for the ones that follow the rule of the first digit being divisible by 1, the first two digits being divisible by 2, etc. I forgot that's not included in the definition for "pandigital" heh. The only one in base 10 is 381,654,729 for example.

Do you mean "the second digit being divisible by 2"? Or are you looking at the product? Your example isn't great here.

Have you tried to write a function to test this? Is it non-functional, or simply inefficient? In either case, what example(s) demonstrate the problem?
