No.
6 is not divisible by 4. Neither is 10, 14, 18, etc.
On the other hand, if a number is divisible by 4, then it is an even number.
The proof is easy. Suppose the number is N = a*4 where a can be even or odd.
Then N = a * 2 * 2 = (a*2) * 2. All numbers (even or odd) when multiplied by 2 give an even number, and so N is necessarily even.

Is a number always divisible by 4 if the sum of the digits is 8?
No. 26 for instance the sum of the digits is 8 but not divisible by 4. 32 the sum of the digits is 5 but divisible by 4 The rules for some other numbers are 2 all even numbers are divisible by 2 3 The sum of the digits is divisible by 3 4 The last 2 numbers are divisible by 4 5 The number ends in a 0 or 5 6 The sum of the digits is divisible by 3 and is even 7 no easy method 8 The last 3 numbers are divisible by 8 9 The sum of the digits is divisible by 9
