Question

Please solve 10th question...

Answer 1

Prime factorization of 8 = 2 * 2 * 2

Prime factorization of 15 = 3 * 5

Prime factorization of 21 = 3 * 7

LCM(8,15,21) = 2 * 2 * 2 * 3 * 5 * 7

                     = 840.



Now, We need to divide 100000 by 840.

840) 100000 ( 119

         840

         -----------

          1600

          840

        ----------------

            7600

            7560

       ---------------

                  40



Therefore the number nearest to 100000 but greater than 100000 = 100000 +(840 - 40)

= 100000 + 800

= 100800.


Hope this helps!
