Answer 2

Hope it helps. There is an image if you see. At first, you have to do simple HCF, then write your numbers, sort out the common factors. If there is just one common factor write it as it is. However, in this case there are two common factors 3 and 5. So, multiply them and you get the answer. Easy as a pie. Thanks for the question.
