lcm(45, 10) = 90
→ the first three common multiples are the first three multiple of their lcm
→ 90, 180, 270.
90, 180, 270
10, 20, 30 15, 30, 45 Common multiples include 30, 60, and 90.
Any multiple of 90.
If that's 45 and 10, common multiples include 90, 180, 270 and so on.
Because 9 is a multiple of 3, the common multiples of 3 and 9 are the multiples of 9. The first 10 common multiples of 3 and 9 are 9, 18, 27, 36, 45, 54, 63, 72, 81, and 90.
45 and 90.
The first five multiples of 15 are 15, 30, 45, 60, 75. For them to be common, they need to be compared to another set of multiples.
15, 30, 45, 60, 75, 90 the first 4 common multiples are 15 30 45 60.
The first 5 multiples of 9 are 9, 18, 27, 36, and 45. For them to be common, they need to be compared to another set of multiples.
90, 180, 270.
The first 10 multiples of 5 are: 5, 10, 15, 20, 25, 30, 35, 40, 45, and 50.
15, 30, and 45 are.
