3 yes, 6 no.
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!
18 and all the multiples of 18.
Not all of them are. Consider 27. 6 and 9 share a lot of common multiples because they share a common factor.
The multiples of 6 is 6,12,18,24,30,36,42,48,54,60,66,72,78,84,90.................. The multiples of 9 is 9,18,27,36,45,54,63,72,81,90,99,108,117,126,135...............
To find the LCM of a number in this case 6 and 9 you find all of their multiples that they share in this caseThe multiples of 6 are 2,3,6
it is 18. 18 is a multiple of all three numbers. multiples of 3: 3,6,9,12,15,18... multiples of 6: 6,12,18... multiples of 9: 9, 18...18
The numbers 3,6 and 9 are all multiples of 3 because 3 can go into all of them evenly.
the first 6 multiples of 9 are 9 , 18 , 27 , 36 , 45 , 54
The multiples of 3 are 3, 6, 9, 12, 15, 18, 21 and so on. The first six multiples of 6 are 6, 12, 18, 24, 30, 36, 42 and so on. Common multiples include all the multiples of 6.
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.
The least common multiples of the number 6 and 9 is 3.
