Find the LCM, then multiply it by 2 and 3.
1, 2, and 53, have their first common multiple of 106.
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.
30,60,90
They are: 20, 40 and 60
36, 72, 108
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.
6, 12 and 18.
20, 40, 60
