Numbers on car number plates

I've been wondering about the numbers on car license plates: some are 3-digit, others are 4-digit or 5-digit numbers.

United States and Canada

In the picture:

Saskatchewan ----------> 546

Michigan ------------------> 6610

Brunswick ----------------> 693

Northwest Territories --> 38542

If we separate them into groups, such as, Group A: the 3-digits license plates, Group B: the 4-digits, Group C: the 5-digits, then,

If we multiply the 3-digits on car number plates together what number are we most likely to get?

Then, if we do do that with the 4-digits, then with the 5-digits.

In this very small sample, we get:

Saskatchewan ............. 5 * 4 * 6 = 120

Brunswick ................... 6 * 9 * 3 = 162

Michigan ..................... 6 * 6 * 1 * 0 = 0

Northwest Territories .... 3 * 8 * 5 * 4 * 2 = 960

I don't have the necessary info to continue.

Somewhere, out there, someone may be able to.
