Answer 1

Explanation:

Short cut method. For any number to be divisible by 8 the last 3-digits should be divisible by 8. Here take 279. The number is not divisible by 8 but 280 is divisible by 8. So just add 1, which is the least number to be added to 289279 to make the new number divisible by 8.

Long method:

First divide 289279 by 8 to get 36159.875. Take the next higher integer, 36160. Multiply 36160 by 8 to get 289280..

From 289280 deduct 289279 to get 1.

So you need to add 1, which is the minimum number to 289279 to be divisible by 8. Correct.

Answer to the question is just add 1
