90, 180, 270, 360
Multiples of 360.
The multiples of 120 are an infinite set that starts with 120, 240, 360, 480, 600, 720, 840, 960, 1080, 1200, and so on.
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.
There are infinite common multiples for a set of numbers. So it is not possible to write down all the common multiples. Some common multiples of 15, 30 and 45 are 90, 180, 270, 360,... There is another way to find common multiples: Write the multiples of LCM(15, 30, 45). Actually the common multiples of a set of numbers are the multiples of their LCM. LCM of 15, 30 and 45 is 90. And the multiples of 90 are 90, 180, 270, 360, 450, 540,... which are the common multiples of 15, 30 and 45.
They would be all the multiples of 360, which is an infinite list.
