Question

5.
What is the least number that should be added to
864 to make it exactly divisible by 21?​

Answer 1

Answer:

The question is least number. So let us divide 864 by 21. The remainder is 3. So now we have two options.

1. Add 21–3=18 to 864

2. Or add -3 to 864

Since negative numbers can also be added and also -3 is comparitively smaller it should be the answer.

864+(-3)=861

But it is not the least number. Consider

864+(-843)=21

Therefore in my opinion, -843 is the least number that can be added to 864 to make it exactly divisible by 21.
