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.
The common multiples of 3, 4, and 8 are numbers that are divisible by all three of these numbers. To find the common multiples, we first list the multiples of each number: Multiples of 3: 3, 6, 9, 12, 15, 18, 21, 24, ... Multiples of 4: 4, 8, 12, 16, 20, 24, ... Multiples of 8: 8, 16, 24, 32, ... The common multiples of 3, 4, and 8 are 24, 48, and so on, as they are the numbers that appear in the lists of multiples of all three numbers.
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.
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
The firt three multiples of 8 are 8, 16 and 24.
8,16,24

It is 120.
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.
