The common multiples of 9, 15, and 20 are an infinite set of multiples of their least common multiple, which is 180. so the common multiples of 9, 15, and 20 are 180, 360, 540, 720, 900, 1080, 1260, 1440, 1620, 1800, 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.
The common multiples of 12 and 30 are numbers that are divisible by both 12 and 30. To find the common multiples, you can list out the multiples of each number and find the numbers that appear in both lists. The common multiples of 12 and 30 are 60, 120, 180, and so on, as these numbers can be evenly divided by both 12 and 30.
The common multiples of 9 and 10 are 90, 180, 270, 360, 450, 540, 630, 720, 810, 900, and so on.
60, 120 and 180
They are 180 and any of its multiples
180
The multiples of 60 include 60, 120 and 180. For them to be common, they need to be compared to another set of multiples.
If that's 45 and 10, common multiples include 90, 180, 270 and so on.
The common multiples of 9, 15, and 20 are an infinite set of multiples of their least common multiple, which is 180. so the common multiples of 9, 15, and 20 are 180, 360, 540, 720, 900, 1080, 1260, 1440, 1620, 1800, and so on.
The Least Common Multiple (LCM) for 20 9 18 is 180.
Don't have a common factor greater than 1.
180
Both 180 and 540 are common multiples of 5, 9 and 12. That is to say they are in the 5-times table, the 9-times table and the 12-times table. But the L in LCM stands for Least. So, since 180 is less than 540, the LCM cannot be 540. You may like to check, for yourself, that no number smaller than 180 is in all the three tables.
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.
An angle greater than 180 degrees is a reflex angle
60 and 180 are two.
