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.
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.
75, 150, 225, 300, 375
75, 150, 225, 300, 375
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.
Common multiples include 75, 150, 225 and so on.
It is 75.
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 is the least common multiple
The first four multiples of five: 5, 10, 15, 20
Any multiple of 75.
CJ:there are no common multiples for 25
