If that's 45 and 10, common multiples include 90, 180, 270 and so on.
lcm(45, 10) = 90 → the first three common multiples are the first three multiple of their lcm → 90, 180, 270.
90, 180, 270
45
10, 20, 30 15, 30, 45 Common multiples include 30, 60, and 90.
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.
The common multiples of 22, 24, and 45 are 3960, 7920, 11880, and so on.
45, 90, 135 and so on.
Any multiple of 45.
Common multiples of 9 and 10 are all of the multiples of 90.
45 1*45 = 45 3*15 = 45
45 and any multiple of 45
