Answer 2

Answer:

9's ten multiples- 9, 18, 27, 36, 45, 54, 63, 72, 81, 90

7's ten multiples- 7, 14, 21, 28, 35, 42, 49, 56, 63, 70

From the above verification, we got '63' as 9's and 7's common multiple.

Step-by-step explanation:

We can find it in a method. The method we usually use to find LCM or HCF will not work here. Therefore, we will multiply 7 and 9 and the product will be considered as their LCM. And in this case, the outcome will be obviously the answer to this question.
