Question

The lcm of numbers is 105 and their hcf is 7 if one of thenumber is 21 find th differnce between th 2 number

Answer 1

Answer:

      LCM*HCF=PRODUCT OF TWO NUMBERS

  let the another number be X

        105*7=21*X

               X=105*7÷21

              X=35

  DIFFERENCE:

                          35-21=14

Answer 2

Given; The lcm of numbers is 105 and their HCF is 7 if one of the numbers is 21

To Find; The difference between the numbers

Solution; Lcm of numbers = 105

If numbers = 7

One number =21

Let the other number =x

Hcf×Lcm =product of numbers

105*7=21*x

105*7/21=x

35=x

Second number=35

Hence the difference between numbers is 14
