The firt three multiples of 8 are 8, 16 and 24.
They are: 24 48 and 72
The first 3 multiples of 4 are: 4, 8, and 12.The first 3 multiples of 9 are: 9, 18, and 27.
A common multiple of 8 and 6 has the form 2 * 2 * 2 * 3 * n = 24n, where n is any whole number. The other factors are necessary to ensure that what you have is indeed a multiple of both 8 (2 * 2 * 2) and 8 (2 * 3). So for the first 3 common multiples you need to replace n with 1, 2 and 3, giving you 24, 48 and 72.
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.
lcm(2, 7) = 14 → first 3 common multiples are: 14, 28, 42; lcm(2, 8) = 8 → first 3 common multiples are: 8, 16, 24; lcm(7, 8) = 56 → first 3 common multiples are: 56, 112, 168; lcm(2, 7, 8) = 56 → first 3 common multiples are: 56, 112, 168.
8, 16, 24
First 3 multiples of: 3: 3, 6, 9 8: 8, 16, 24 9: 9, 18, 27 72, 144, 216
The common multiples of an set of numbers are the multiples of their lowest common multiple. lcm(7, 8, 9) = 504 → the first 3 common multiples of 7, 8, 9 are 504, 1008, 1512.
24, 48, 72
They are the multiples of 3*8 = 24
8,16,24
4, 8, 12
72
It is 120.
The firt three multiples of 8 are 8, 16 and 24.
The first three multiples of 4 are 4, 8 and 12. For them to be common, they need to be compared to another set of multiples.
