Answer 1

Answer:

9

Step-by-step explanation:

This questions seems to be an application of HCF. To quickly find the HCF, simply find the difference between 675 and 540 which 135. The HCF will be 135 or factors of 135, but in this case 135 is a factor of both and all the highest one at it, ie HCF is 135.

675/135 = 5

540/135 = 4

So, answer is 5+4 = 9.

Factors of 135 wlll also divide these 2 numbers but since the factors of 135 are smaller than 135, they will not give the minimum number required in the question.
