18, 36, 54
The common multiples of 22, 24, and 45 are 3960, 7920, 11880, and so on.
630 and all the multiples of 630.
The lowest common multiple is 18. The first four common multiples are thus the first four multiples of 18 and are: 18, 36, 54 and 72.
18, 36, 54 and so on. 45, 90, 135 and so on. 63, 126, 189 and so n.
The first 5 multiples of 9 are 9, 18, 27, 36, and 45. For them to be common, they need to be compared to another set of multiples.
18, 36, 54
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.
Yes, 9x2=18 and 9x5=45
The common multiples of 18 and 24 are 72 and 144.
The common multiples of 22, 24, and 45 are 3960, 7920, 11880, and so on.
They're all multiples of 9.
630 and all the multiples of 630.
All multiples of 36 are multiples of 18.
Multiples of 15 include 15, 30 and 45. For them to be common, they need to be compared to another set of multiples.
Yes
There are infinity of them Here are some common multiples of 9: 18, 27, 36, 45, 54, 63, 72, 81, 90, 99, 108, 117, 126
