write the first three common. multiples of 3,4,5
20 is the smallest common multiple of 4, 5, and 10, and thus the first. Thus, the first three common multiples of 4, 5, and 10 are 20, 40 and 60.
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
60 120 180
20, 40, 60
180, 360, 540
60, 120, 180
20, 40, 60
60, 120, 180
60, 120, 180
12, 24, and 36
The common multiples of 4 and 5 are 20, 40, 60, 80,100 and so onGet the least common multiple of the two. All other common multiples are multiples of this least common multiple.Any multiple of 20.
