- When it comes to prime numbers, each prime number is its own factor unless we consider 1.

- If A, B, and C are all distinct prime numbers, they do not share any factors other than 1.

- Option 1: 7 - This option is incorrect. Prime numbers do not share common factors above 1, unless specifically stated that they include 7.

- Option 2: 0 - This doesn't make sense in context because 0 isn't a factor of any number.

- Option 3: 5 - It would only be correct if 5 were one of the numbers and they weren't distinct primes.

- Option 4: 1 - Correct! The only common factor among distinct prime numbers is 1.
