Multiples of 54 include 54, 108 and 162. For them to be common, they need to be compared to another set of multiples.
To find the common multiples of 3, 6, and 18, we need to list out the multiples of each number and find the numbers that appear in all three lists. The multiples of 3 are 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, and so on. The multiples of 6 are 6, 12, 18, 24, 30, and so on. The multiples of 18 are 18, 36, 54, 72, and so on. The first three common multiples of 3, 6, and 18 are 18, 36, and 54.
The common multiples of 1 and 6 are the same as the multiples of 6. They are 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, and so on.
Short answer: There is none. There is not a least common multiple of a single number, such as 54, because there cannot be any form of common multiple without two or more numbers to compare. Common multiples are multiples that the numbers being compared have in common. The least common multiple is the smallest multiple that all the numbers being compared have in common. Thus, since there are not two or more numbers to compare, there is not a least common multiple. The lowest common multiple of 54 depends upon the other number(s) with which it has COMMON multiples and is one of the multiples of 54. The common multiples of 54 depends upon the other numbers with which 54 has COMMON multiples and are the multiples of the least common multiples between 54 and the other number(s).
36, 54, 72 and so on.
It is 54
The first three common multiples are 18, 36, and 54.
Multiples of 6: 6, 12, 18, 24, 30, 36, ................ Multiples of 10: 10, 20, 30, 40, ................ 30 is the LCM (least common multiple) of 6 and 10. correct but LCM stands for lowest common multiple...
Since 30 is a multiple of 6, all multiples of 30 are common.
Multiples of 9 are 9 18, 27, 36, 45, 54, 63, 72, 81, 90, 99, 108, 117, 126, 135, 144, 153, 162, 171, 180... Multiples of 30 are 30, 60, 90, 120, 150, 180... Common multiples of 9 and 30 are 90, 180... The Least Common Multiple of 9 and 30 is 90.
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.
The multiples of 3 up to 30 are: 3,6,9,12,15,18,21,24,27,30.The multiples of 5 up to 30 are: 5,10,15,20,25,30.The only common multiples are 15 and 30.The LCM is: 30
