150, 300, 450 and so on.
Multiples of 2: 2, 4, 6, 8, 10, 12, 14, ... Multiples of 5: 5, 10, 15, 20, 25, 30, ... Multiples of 10: 10, 20, 30, 40, 50, ... So the LCM (Least Common Multiple) is 10.
There is an infinite number of common multiples for 15 and 25. A common multiple of any two or more numbers is any number into which each of two or more numbers can be divided evenly (zero remainder). However, the least or lowest common multiple (LCM) of 15 and 25 is 75.
The LCM of 10, 15, and 25 is 150.
Thye all end in either 0 or 5 5 10 15 20 25 30 35 40 etc
Use a multiple chart. 15...15,30,45,60,75,90,105,120,135,150 25...25,50,75,100,125,150,175 10...10,20,30,40,50,60,70,80,90,100,110,120,130,140,150,160 The multiples that are the same are Common Multiples. The one that is the smallest is the lowest common multiples. 150 is the LCM. That is your answer
150
The first five multiples of 5 are 5, 10, 15, 20 and 25. For them to be common, they need to be compared to another set of multiples.
10 and 15 15 and 20 20 and 25
The common multiples of 15 and 25 are all multiples of their LCM, which is 75. So, the common multiples are 75, 150, 225, 300, 375, 450, 525, 600, and so on.
The first four multiples of five: 5, 10, 15, 20
75
Common multiples of 15 and 25 are all multiples of 75. That is because 75 is the least common multiple of 15 and 25. So they are 75, 150, 225, etc. Just keep multiplying 75 by 4,5,6...etc.
Least Common Multiple (LCM) for 10 25 is 50
Common multiples include 75, 150, 225 and so on.
Multiples of 5 include 5, 10, 15 and 20. For them to be common, they need to be compared to another set of multiples.
