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.
Use the methods you learned to get the least common multiple. Then multiply this result by 2, and by 3, to get the next multiples.
write the first three common. multiples of 3,4,5
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.
4, 8 and 12 are the first 3 common multiples of 2 and 4
The first 3 common multiples of 4 and 12 are: 12, 24, 36
The first three multiples of 2 are 2, 4, 6. For them to be common, they need to be compared to another set of multiples.

4=22 10=2x5 So the LCM of 4 and 10 is 22x5=20 and the next multiples of both 4 and 10 are multiples of 20
They are the first three multiples of their lowest common multiple: 36, 72, 108.
