72, 144, 216 and so on.
The least common multiples of the number 6 and 9 is 3.
8 and 9 are corpime, so their first common multiple is their product. The next common multiples are simply the multiples of that first multiple.The first three common multiples are therefore 72, 144 and 216.
Just 72. It was found by multiplying 8 and 9. --------------------------------------- The common multiples of two numbers are the multiples of their lowest common multiple. LCM(8, 9) = 72 The common multiples of 8 and 9 are 72, 144, 216, ... The only common multiples less than 100 are 72 only.
The common multiples of an set of numbers are the multiples of their lowest common multiple. lcm(7, 8, 9) = 504 → the first 3 common multiples of 7, 8, 9 are 504, 1008, 1512.
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
Lowest Common MultipleThe smallest common multiple of two or more numbers is called the lowest common multiple (LCM). E.g. Multiples of 8 are 8, 16, 24, 32, …Multiples of 3 are 3, 6, 9, 12, 15, 18, 21, 24, …In general:To find the lowest common multiple (LCM) of two or more numbers, list the multiples of the larger number and stop when you find a multiple of the other number. This is the LCM.Example 3Find the lowest common multiple of 6 and 9.Solution:List the multiples of 9 and stop when you find a multiple of 6.Multiples of 9 are 9, 18, …Multiples of 6 are 6, 12, 18, …Example 4Find the lowest common multiple of 5, 6 and 8.Solution:List the multiples of 8 and stop when you find a multiple of both 5 and 6.Multiples of 8 are 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96, 104, 112, 120, …Stop at 120 as it is a multiple of both 5 and 6.So, the LCM of 5, 6 and 8 is 120.
504 is the least common multiple of 7, 8 and 9. All numbers that are multiples of 504 are multiples of 7, 8 and 9 as well
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.
Least Common Multiple (LCM) for 8 9 is 72.
