Question

Find the greatest numbers that divide 51 and 79 leaving 9 as remainder in both cases

​

Answer 1

Answer:

14 is the greatest number that divide 51 and 79 leaving 9 as remainder in both cases

Answer 2

Answer:

If 9 is the remainder then the number -9 will be divisible by the divisor.

Therefore 51 - 9 = 42

79 - 9 = 70

Now we are supposed to find the HCF as the greatest number is asked

=14

Therefore, the number is 14
