Multiples of 5 include 5, 10, 15, 20 and so on. For them to be common, they need to be compared to another list of multiples.
5,10,15,20 and 25
5,10,15,20,25
5,10,15,20,25,30,35,40,45,50
There are infinitely many multiples of 5 so it is not possible to list them. They are all of the form 5*k where k is an integer.
5, 10, 15, 20
The first three multiples of 3 and 5 are 15, 30 and 45.
LCM = 30
hmm, 3,6,9,12,15 maybe
It is impossible to list the last five multiples of anything. Numbers don't stop.
The multiples of 3 up to 30 are: 3,6,9,12,15,18,21,24,27,30.The multiples of 5 up to 30 are: 5,10,15,20,25,30.The only common multiples are 15 and 30.The LCM is: 30
One way is to list the multiples of each number. Example: 3 and 5. 3,6,9,12,15,18,21,24,27,30,33 5,10,15,20,25,30,35 15 and 30 are common multiples of 3 and 5.
