They are all multiples of 3.
Multiples of 3 are 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, and so on. Multiples of 5 are 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, adn so on. The common multiples of 3 and 5 are all of the multiples of 15, i.e. 15, 30, 45, 60, 75, 90, and so on.
Here are all 13 of them: 15, 30, 45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195
The first six multiples of 3 are 3, 6, 9, 12, 15, and 18.
3, 6, 9, 12, 15, 18, 21, 24, 27, 30. 5, 10, 15, 20, 25, 30, 35, 40, 45, 50.
The multiples of 9 are 9, 18, 27, 36, 45 and so on. The multiples of 15 are 15, 30, 45, 60, 75 and so on. The GCF of 9 and 15 is 3.
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
All multiples of 90.
They are all multiples of 3.
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.
Multiples of 3 are 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, and so on. Multiples of 5 are 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, adn so on. The common multiples of 3 and 5 are all of the multiples of 15, i.e. 15, 30, 45, 60, 75, 90, and so on.
4 and 8 are multiples of 2. 6 and 9 are multiples of 3. 40 and 50 are multiples of 10.
The common multiples of 9, 15, and 20 are an infinite set of multiples of their least common multiple, which is 180. so the common multiples of 9, 15, and 20 are 180, 360, 540, 720, 900, 1080, 1260, 1440, 1620, 1800, and so on.
There are 5 multiples of 9. There are 4 multiples of 12. There is 1 number that is a multiple of both, 36.
The LCM of 6, 9, and 15 is 90.
3
The LCM of 3 and 5 is 15. The multiples of 3 are , 6, 9, 12, 15, and so on. The multiples of 5 are 5, 10, 15, and so on. The LCM is 15.
