Answer 2

Answer:

The largest six-digit number exactly divisible 45 = 999990

Step-by-step explanation:

To find,

The largest 6-digit number is 999999 exactly divisible by 45

Recall the concept

Division algorithm

Dividend = Divisor ×Quotient +remainder

When we divide 999999 by 45 by actual division we get

        22222 →Quotient  

       _______

45 |   999999

         90

       _______

           99

           90

          ______

             99

             90

            ______

               99

               90

             ______

                9 →remainder

Here,

dividend = 999999

Divisor = 45

quotient = 22222

Remainder = 9

Then by division algorithm we have,

999999 = 22222×45 + 9

999999 - 9 = 22222×45

999990 = 22222×45

Then we can conclude that, 999990 is exactly divisible by 45

Hence, the largest six digit number exactly divisible 45 = 999990
