Problem Statement:
Find the least number that should be subtracted from 80600 so that the result is exactly divisible by 456.

Solution:
To solve the problem, we need to follow the below steps:

1. Find the remainder when 80600 is divided by 456.
2. Subtract the remainder obtained in step 1 from 456.
3. The result obtained in step 2 is the least number that should be subtracted from 80600 to make it divisible by 456.

Let's solve the problem step by step.

Step 1: Find the remainder when 80600 is divided by 456.

We know that if a number is divisible by another number, then the remainder is 0. Therefore, we need to find the remainder when 80600 is divided by 456.

80600 ÷ 456 = 177 R 308

So, the remainder is 308.

Step 2: Subtract the remainder obtained in step 1 from 456.

456 - 308 = 148

So, the least number that should be subtracted from 80600 to make it divisible by 456 is 148.

Step 3: Verify the answer.

Let's subtract 148 from 80600 and check if the result is divisible by 456.

80600 - 148 = 80452

80452 ÷ 456 = 176

So, the answer is correct.

Final Answer: The least number that should be subtracted from 80600 to make it divisible by 456 is 148.
