Multiples of 3 include 3, 6, 9, 12, 15, and so on. To be common, they need to be compared to another set of multiples.
5: 5, 10, 15 9: 9, 18, 27 If you are looking for the lowest common multiple between 5 and 9 it would be 45. By the way multiples are just counting by the number itself. e.g. 5, 10, 15, 20, 25, 30, 35 (just count by fives or if the number was anything else count by that number)
Any multiple of 15.
To find the common multiples of 2, 3, and 9, we first need to list out the multiples of each number. The multiples of 2 are 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, and so on. The multiples of 3 are 3, 6, 9, 12, 15, 18, 21, 24, 27, and so on. The multiples of 9 are 9, 18, 27, 36, 45, 54, 63, 72, 81, and so on. The first three common multiples of 2, 3, and 9 are 18, 36, and 54.
To find a number that is not a common multiple of 4 and 9, we need to consider the multiples of each number. The multiples of 4 are 4, 8, 12, 16, 20, 24, ... and the multiples of 9 are 9, 18, 27, 36, 45, ... The first number in the list of multiples of 4 that is not a multiple of 9 is 4. Therefore, 4 is a number that is not a common multiple of 4 and 9.
All multiples of 90.
The Least Common Multiple of 9 and 15 is 45.
The lowest common multiple of 15, 9 and 3 is 45 but the individual multiples of 15, 9 and 3 can go on for evermore
The biggest common divisor of 9 and 15 is 3. To find the least common multiples of 9 an 15 you should multiply these numbers and divide the result by their biggest common divisor. 9x15/3=45
3
The LCM of 6, 9, and 15 is 90.
It is: 360
To find common multiples you need the multiples of at least 2 numbers for example: To find multiples of 15 you have to do this: 15 x 1 = 15 15 x 2 = 30 15 x 3 = 45 15 x 4 = 60 15 x 5 = 75 The first five multiples of 15 are 15, 30, 45, 60, 75 Now find the multiples of another number like lets say 9 9 x 1 = 9 9 x 2 = 18 9 x 3 = 27 9 x 4 = 36 9 x 5 = 45 The first five multiples of 9 are 9, 18, 27, 36, 45 Now compare the results of the two numbers 15 and 9 and you can see they have a common multiple of 45. Normally you want to continue finding multiples for each number until you have at least 2 common multiples.
3- 3, 6, 9, 12, 15, 18 5- 5, 15, 20, 25, 30 answer 15
The multiples of 3 are: 3, 6, 9, 12, 15, 18 etc ...The multiples of 5 are: 5, 10, 15, 20, etc ...The multiples of 15 are: 15, 30, 45, etc ...The lowest common multiple of 3, 5, and 15 is 15, so the LCM = 15
4, 8, 12 and so on. 9, 18, 27 and so on. 15, 30, 45 and so on. Common multiples include 180, 360, 540 and so on.
Any multiple of 45.
