What is the least number that must be added to the greatest 6-digit number so that the sum will be exactly divisible by 294?

Explanation

Given: The largest six-digit number exactly divisible by 294 Formula used: Required largest n-digit no. = [(Largest n-digit no.) – (Remainder left when the largest n-digit no. is divided by the provided divisor)]. Calculation: The largest six-digit number = 999999 Now, The largest six-digit number divisible by 294 ⇒ (999999/294) Then, we get remainder = 105 ⇒ 294 - 105 ⇒ 189 The answer is 189.
