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 common multiple of 4, 5, and 10 is their least common multiple (LCM), which is the smallest number that is a multiple of all three numbers. The LCM of 4, 5, and 10 is 20. The next common multiple would be the next multiple of 20, which is 40. The third common multiple would be the next multiple of 20, which is 60.
They are the first three multiples of their lowest common multiple: 36, 72, 108.
