The first three common multiples of eight and 12 are 1, 2, and 4. Three is not included because there is nothing that you can multiply with it to make 8 evenly.
The common multiples of any two or more numbers are the multiples of their lowest common multiple.lcm(3, 4, 5) = 60→ first three common multiples are:60 x 1 = 6060 x 2 = 12060 x 3 = 18060, 120, 180
There are more than 3 multiples for the number 28. You can use 28 times 1, 4 times 7 and 7 times 4.
factoring 5 factored =1*5 12 factored =2*2*3 no common factor so the LCM is 60 the next multiples would be 120 and 180

Multiples of 1 include 1, 2 and 3. For them to be common, they need to be compared to another set of multiples.
