There are 10 digits, 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9
192 ways
numbers that are divisible by 4 is either: 4n or numbers in which the number formed by last two digits are divisible by 4
The number formed by the last three digits have to be divisible by 8.
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.
if the number formed by the last two digits is divisible by 4, then the whole number will be divisible by 4 for example, 932 is divisible by 4 because 32 is divisible by 4 19935 is not divisible by 4 because 35 is not divisible by 4 (note: if the last two digits are 00, the number is divisible by 4)

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.
If the number formed by the last three digits is divisible by 8. Alternatively, if the number is divisible by 2, the quotient is divisible by 2 and that quotient is divisible by 2.
If the last three digits of a number are divisible by 8, the whole number is divisible by 8.

The number formed by the last three digits have to be divisible by 8.
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.
If the number formed by the last three digits is divisible by 8. This requires that: if the digit in the hundreds place is even, the last two digits must form a number divisible by 8 and if the digit in the hundreds place is odd, the last two digits must form a number divisible by 4 but not by 8.
if the number formed by the last two digits is divisible by 4, then the whole number will be divisible by 4 for example, 932 is divisible by 4 because 32 is divisible by 4 19935 is not divisible by 4 because 35 is not divisible by 4 (note: if the last two digits are 00, the number is divisible by 4)
There are 2000 such numbers.
if the last 3 digits are divisible by 8,so is the number. Ex.: 9 is not because 009 is not. 6008 is because 008 is.
If repetition of digits isn't allowed, then no13-digit sequencescan be formed from only 5 digits.
