Solution
The 6-digit number formed by repeating a 3-digit number is always exactly divisible by 13 and 7. This is because the number can be expressed as 1001 * ABC, where ABC is the 3-digit number. Since 1001 is a multiple of 13 and 7, any number of this form is also a multiple of 13 and 7. Therefore, the correct answer is "13 only" and "7 only".
