986541
...Any number that has 20 digits! For example, 10,000,000,000,000,000,000 (10 quintillion)
8765 and 8756 and 8675 There are 24 total.
Numbers formed should be of at least 3 digits means they may be of 3 digits, 4 digits, 5 digits or 6 digits. There are 6 choices for digit in the units place. There are 5 and 4 choices for digits in ten and hundred’s place respectively. So, total number of ways by which 3 digits numbers can be formed = 6.5.4 = 120 Similarly, the total no.of ways by which 4 digits numbers can be formed = 6.5.4.3 = 360. the total no. of ways by which 5 digits numbers can be formed = 6.5.4.3.2 = 720. The total no.of ways by which 4 digits numbers can be formed = 6.5.4.3.2.1 = 720. So, total no.of ways by which the numbers of at least 3 digits can be formed = 120 + 360 + 720 + 720 = 1920.
It is 120 if the digits cannot be repeated.
There are 3,265,920 numbers that can be formed using all the digits. The answer to the question will depend on which one of these.
Whole numbers are divisible by 4 if the number formed by the last two individual digits is evenly divisible by 4. For example, the number formed by the last two digits of the number 2628 is 28, which is evenly divisible by 4 so the number 2628 is evenly divisible by 4.

6*6*3 = 108 numbers.
Numbers are divisible by 8 if the number formed by the last three individual digits is evenly divisible by 8. For example, the last three digits of the number 3624 is 624, which is evenly divisible by 8 so 3624 is evenly divisible by 8.
There are 2000 such numbers.
There are 2000 such numbers.
The number 1234567890 can create about 39 of 40 4 digit numbers.
numbers that are divisible by 4 is either: 4n or numbers in which the number formed by last two digits are divisible by 4
Assuming the question refers to the digits 1, 2, ... , 9 the answer is 1344 numbers.
