Find the LCM, then multiply it by 2 and 3.
1, 2, and 53, have their first common multiple of 106.
30,60,90
36, 72, 108
They are: 20, 40 and 60
All the common multiples of a set of numbers are the multiples of their lowest common multiple: lcm(5, 8, 10) = 40 → first three common multiples are 40, 80, 120
the first three common multiple of 6 and 8 are : 28,48,72
The way to solve this is as follows:Find the least common multiple of the two numbers.Multiply this least common multiple by 2 and by 3, to get the next two common multiples.
48, 96, and 144 is.
100 200 and 300
20, 40, 60
6, 12 and 18.
