How to Find the Biggest Number of Four Digits Divisible by 38?

Published in Number Theory 1 min read

The largest four-digit number divisible by 38 is 9994.

Here's how we arrive at that conclusion:

  • Understanding the Problem: We need to find the largest number with four digits that can be divided by 38 without leaving a remainder.

  • Largest Four-Digit Number: The biggest four-digit number is 9999.

  • Finding the Divisible Number: We can find the required number in a couple of ways:

    1. Division and Adjustment:

      • Divide the largest four-digit number (9999) by 38. This results in approximately 263.13.
      • Take the integer part of that result (263) and multiply it by 38: 263 * 38 = 9994.
      • Since 9994 is less than 9999 and divisible by 38, this is our answer.
    2. Working Backwards:

    • Start with 9999 and incrementally subtract 1 and check divisibility by 38. This would take more time but would give the same result.
  • Reference Confirmation: The provided reference explicitly states that the biggest four-digit number divisible by 38 is 9994 (16-Sept-2018).

Therefore, the answer is 9994.
