Oh, dude, 9 and 21 both go into numbers that are multiples of both 9 and 21. So, like, they can go into numbers like 63, 126, 189, and so on. It's just basic math, nothing too mind-blowing.
7 and 9 are two numbers that go into 63.
1 goes into both 49 and 63, as well as 7does also.
The numbers that go into 45 are 1, 5, 9, 45
Both 9 and 3 go into both numbers. 45/54 = 5/6 45/54 = 15/18

The LCM is: 630just multiply 90*63 and what i do is go google and look up least common multiple calculator and there you have different options and pick the one that best fits your answer
