Question

divide the greatest number of 9 digit by the greatest number of 3 digit

Answer 1

First of all we will find the LCM of 5, 9, and 15 which gives the value 45.

Now, 45*22=990 which is the greatest three digit no and it is divisible by 5, 9, and 15.

Therefore leaving remainder 3 will ultimately lead the result to:

990 + 3=993
