Three 3-digit Positive Integers (Posted on 2023-07-02) Difficulty: 3 of 5
Charmaine has written down three 3-digit positive integers which between them contains exactly 9 distinct digits.

Among these three positive integers:

  • There is at least one that is divisible by 2.
  • There is at least one that is divisible by 3.
  • There is at least one that is divisible by 4.
  • There is at least one that is divisible by 5.
  • There is at least one that is divisible by 6.
  • There is at least one that is divisible by 7.
  • There is at least one that is divisible by 8.
  • There is at least one that is divisible by 9.
In addition, it is known that all the three positive integers are divisible by 11.

What are the three 3-digit integers posited by Charmaine?
