Not all of them are. Consider 27. 6 and 9 share a lot of common multiples because they share a common factor.
Yes it is... Multiples of 3 & 6 are 3, 6, 9, 12, 15 & 18
18 and 36.
Well, honey, let me break it down for you. No, not all multiples of 9 are multiples of 6. See, multiples of 9 are numbers like 9, 18, 27, and so on, while multiples of 6 are numbers like 6, 12, 18, and so forth. So, while 18 is both a multiple of 9 and 6, not all multiples of 9 will be multiples of 6. Hope that clears things up for ya!
are 90 180 270
The least common multiples of the number 6 and 9 is 3.
Not all of them are. Consider 27. 6 and 9 share a lot of common multiples because they share a common factor.
Multiples of 90
18
The common multiples of 6 and 9 are the infinite set of multiples of their LCM, which is 18. So the common multiples of 6 and 9 are 18, 36, 54, 72, 90, 108, 126, 144, 162, 180, and so on.
3
The first three multiples of 3 are 3, 6, 9 The first three multiples of 9 are 9, 18, 27 As the lowest common multiples of 3 and 9 is 9, the common multiples of 3 and 9 are the multiples of 9, thus: The first three common multiples of 3 and 9 are 9, 18, 27
The LCM of 6, 9, and 15 is 90.
There are plenty of common multiples, but only one can be the least; thus the least common multiple of 3, 6, 9 is 18.
The LCM is: 18
Any multiple of 18.
180
