Week #24, 2022
Question:
Phil wrote down a six-digit number on the board, and then Caleb erased two of the digits. What remains on the board is 234__6__. Phil remembers that the original number is divisible by 2, 3 and 5. What is the greatest possible value of Phil’s original number?
Answer:
The number being divisible by both 2 and 5 means the ones digit must be 0. To be divisible by 3, the sum of the digits must be divisible by 3: 2 + 3 + 4 + h + 6 + 0 = 15 + h, so the hundreds digit must be divisible by 3, thus 0, 3, 6 or 9. The largest of these, 9, yields the greatest possible overall value for the original number, 234960.
