Answer 1

DEAR MATE,

HERE IS YOUR ANSWER..

The least common multiple of  7  is 42.

Now, the largest 5 digit number is 99999.

So let's divide 99999 by 42 :

99999= 2380×42+39

Here we get quotient 2380 and remainder 39.

So the largest 5 digit multiple of 42 is 2380×42=99960.( as the next multiple of 42 which is 2381×42=100002 , is a 6 digit number)

So, the largest 5 digit number which is exactly divisible by  7 and  is 99960.
