None. 3 digit numbers are not divisible by 19 digit numbers.
To determine the number of 2-digit numbers where the units digit is greater than the tens digit, we need to consider the possible combinations. The tens digit can range from 1 to 9, while the units digit can range from 0 to 9. If the units digit is greater than the tens digit, there are 36 possible combinations (9 choices for the tens digit and 4 choices for the units digit).
The answer will depend on how many digits there are in each of the 30 numbers. If the 30 numbers are all 6-digit numbers then the answer is NONE! If the 30 numbers are the first 30 counting numbers then there are 126 combinations of five 1-digit numbers, 1764 combinations of three 1-digit numbers and one 2-digit number, and 1710 combinations of one 1-digit number and two 2-digit numbers. That makes a total of 3600 5-digit combinations.
Number of 7 digit combinations out of the 10 one-digit numbers = 120.
Only one . . . 999 .
With 123 digits you can make 123 one-digit numbers.
None. The sum of one digit can't be twice the size of the digit.

The possibilities are all the counting numbers from the largest 16-digit one to the largest 17-digit one.99,999,999,999,999,999 minus 9,999,999,999,999,999 = 90,000,000,000,000,000
