A 6-digit number consisting of consecutive natural numbers is always divisible by 3. The sum of consecutive natural numbers is always divisible by 3. If the number is divisible by 3, then the sum of its digits will also be divisible by 3. An example of a 6-digit consecutive number is 123456 (1 + 2 + 3 + 4 + 5 + 6 = 21, divisible by 3).
Hence, the correct answer is 3.
