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.

Find the multiples of 27 and 15:Multiples of 27:..27 x 5 = 135Multiples of 15:..15 x 9 = 135Thus, 135 is the same common denominator for 27 and 15.

Each common multiple of 9 and 10 occurs exactly once (in the list of common multiples), so there is no common multiple that occurs the most. All common multiples of 9 and 10 are the multiples of their least common multiple which is 90.

The way to solve this is as follows:Find the least common multiple of the two numbers.Multiply this least common multiple by 2 and by 3, to get the next two common multiples.

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.

Any multiple of the LCM (15) is common.

The least common multiple of 3 and 9 is 9. because: Multiples of three are: 3, 6, 9, 12, 15... Multiples of nine are: 9, 18, 27, 36.... The Least Common Multiple (LCM) there in both of the numbers is 9.

The least common multiples of the number 6 and 9 is 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.

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.

You need at least two numbers to compare multiples.
