Answer:

5 (all of them)

Explanation:

The sums of digits are ...

6+4+8 = 18

8+4+6 = 18

1+2+6 = 9

6+1+2 = 9

5+7+6 = 18

When the sum of digits is a multiple of 9, the number is divisible by 3 and 9.

When the number is also even (as all of these are), it is also divisible by 6.

All 5 of these numbers are divisible by 3, 6, and 9.
