A number is divisible by 234 if:its last digit is 0, 2, 4, 6 or 8; andthe sum of its digits (the calculation repeated if required), is divisible by 9; andthe result of nine times the last digit subtracted from the number formed by the rest (the calculation repeated if required) is divisible by 13.

It is 120 if the digits cannot be repeated.
numbers that are divisible by 4 is either: 4n or numbers in which the number formed by last two digits are divisible by 4
6*6*3 = 108 numbers.
Assuming no repeated digits, lowest first, 20; in any order 120; Allowing repeated digits: 216
6*5*4*3*2*1=720 possible numbers
There are 5! = 120 such numbers.

It is 120 if the digits cannot be repeated.
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.
