Any multiple of 9.
The first 5 common multiples are the first 5 multiples of their lowest common multiple (LCM) LCM(9, 10) = 90 → first 5 common multiples are 90, 180, 270, 360, 450.
8 and 9 are corpime, so their first common multiple is their product. The next common multiples are simply the multiples of that first multiple.The first three common multiples are therefore 72, 144 and 216.
The first 3 multiples of 9 are: 9, 18, and 27.The first 3 multiples of 12 are: 12, 24, and 36.
The common multiples of any two (or more) numbers are multiples of their lowest common multiple (lcm). lcm(9, 11) = 99 → first five common multiples are: 99, 198, 297, 396, 495
The first three multiples of 3 are 3, 6, 9 The first three multiples of 9 are 9, 18, 27 As the lowest common multiples of 3 and 9 is 9, the common multiples of 3 and 9 are the multiples of 9, thus: The first three common multiples of 3 and 9 are 9, 18, 27
If that's 9, 14 and 21, the first three common multiples are 126, 252 and 378.
9, 18, 27
9, 18, 27
The first three are 9, 18, and 27.
18,36,and 54
They are: 3, 6 and 9
63
They are the first three multiples of their lowest common multiple: 36, 72, 108.
You can't have common multiples if they have nothing to be in common with however the first 3 multiples of 9 are 9,18 and 27 Think of just your times tables when finding out Multiples to find the first 5 multiples just count by 9's until you have said 5 numbers and Bingo
117, 234, 351
72, 144 and 216
