40 and 120, yes. The rest, no.
The multiples of 24 are 24, 48, 72 and so on. The multiples of 40 are 40, 80, 120 and so on. The common multiples of 24 and 40 are 120, 240, 360 and so on.
All multiples of 120 are multiples of both 40 and 24, because 120 contains all the factors of 40 (23*5) and 24 (23*3). Some examples of multiples are 120, 240, 360, and 600.
Multiples of 40 include 40, 80, 120 and so on. For them to be common, they need to be compared to another set of multiples.
Here is one example: 20, 40, 60, 80, 100, 120, 140, 160, 180.
Not all multiples of 40 are multiples of 80. Only the even multiples of 40 are also multiples of 80. The odd multiples, e.g. 40, 120, 200, 280, and 360, are not multiples of 80.
The multiples of 20 are: 20, 40, 60, 80, 100, 120, 140, etc ...The multiples of 30 are: 30, 60, 90, 120, 150, etc ...The multiples of 40 are: 40, 80, 120, 160, etc. ...The lowest multiple common to 20, 30, and 40 is 120, so the LCM = 120
The first six multiples of 40 are 40, 80, 120, 160, 200, and 240.
The LCM of 40 and 25 is: 200The least common multiple of 25 and 40 is 200.You can find this by determining the multiples of each number:25: 25, 50, 75, 100, 125, 150, 175, 20040: 40, 80, 120, 160, 200
It is 120
40, 80, 120, 160, 200.
25 with 40 remaining 3,040 - 40 = 3,000 = 120 x 25
Multiples of 20 are 20, 40, 60, 80, 100, 120, 140, 160, 180, 200…Multiples of 25 are 25, 50, 75, 100, 125, 150, 175, 200… Common multiples of 20 and 25 are 100, 200, 300, 400...
