A finite number of digits refers to any numerical representation that has a limited count of digits, such as whole numbers, integers, or specific decimal numbers that terminate. For example, the number 1234 has four digits, while the decimal number 3.14 has three digits before the decimal point and two after it, making a total of five digits. In contrast, irrational numbers like π or repeating decimals like 1/3 have infinite digits.
you take the four digits and multiply 4 by 4 you get 16 digits
The four-digit numbers that can be formed using the digits 6, 7, 8, and 9, without repetition, are all the permutations of these four digits. There are 24 possible combinations, including numbers like 6789, 6798, 6879, and so on. Essentially, any arrangement of these four digits constitutes a valid four-digit number.

If the last two digits of a number are divisible by four, the whole number is divisible by four.
It is usually 4 digits. Some banks offer pin numbers that are more than 4 digits long.
Any pair of digits (not including 0), can be used to generate 14 four-digit numbers. If one of the digits is 0, only seven will start with a non-zero digit.

If the digits are all different then 18. Otherwise, 192.
