Correct answer: C

Step-by-Step Solution

To find the smallest 5-digit number divisible by 456, follow this systematic approach:

  1. Identify the smallest 5-digit number:

    • The smallest 5-digit number is 10,000.

  2. Divide by the target divisor:

    • Divide 10,000 by 456 to see how close it is to the next multiple.

    • 10,000 ÷ 456 = 21 with a remainder of 424.

    • This means 10,000 is 424 units past a multiple of 456.

  3. Determine the adjustment:

    • To reach the next multiple of 456, calculate how much more needs to be added to the remainder:

    • 456 - 424 = 32.

  4. Find the required number:

    • Add this difference to the smallest 5-digit number:

    • 10,000 + 32 = 10,032.
