45 and 90
The first 5 common multiples are the first 5 multiples of their lowest common multiple (LCM) LCM(9, 10) = 90 → first 5 common multiples are 90, 180, 270, 360, 450.
The first 5 multiples of 9 are 9, 18, 27, 36, and 45. For them to be common, they need to be compared to another set of multiples.
Oh, isn't that just lovely! To find the common multiples of 2, 5, and 9, we can start by listing the multiples of each number. For 2, we have 2, 4, 6, 8, 10, and so on. For 5, we have 5, 10, 15, 20, and so forth. And for 9, we have 9, 18, 27, 36, and on it goes. The common multiples are the numbers that appear in the list of multiples for all three numbers, such as 90 and 180. Just like painting a happy little tree, finding common multiples can be a peaceful and joyful process.
The LCM of 5 & 9 is... 45
90. All numbers that are multiples of 3, 5 & 9 are multiples of their lowest common multiple lcm(3, 5, 9) = 45 → multiples of 45 between 49 and 95 is 2 x 45 = 90.
LCM = 9x5x2 = 90 all multiples are 90, 180, 270, etc
You can't have common multiples if they have nothing to be in common with however the first 3 multiples of 9 are 9,18 and 27 Think of just your times tables when finding out Multiples to find the first 5 multiples just count by 9's until you have said 5 numbers and Bingo
Since the lowest common multiple of 9 and 2 is 18, all of the common multiples of 9 and 2 are multiples of 18. The first five are: 18, 36, 54, 72, 90 Since 9 is odd thean there are going to be odd numbers, which are not multiples of two.
Oh, what a happy little question! When we talk about multiples, we're looking at numbers that both 2 and 9 can be divided into evenly. The common multiples of 2 and 9 are numbers like 18, 36, 54, and so on - just like little friends skipping along together in the meadow.
The Least Common Multiple (LCM) for 9 5 99 is 495.

There can only be one greatest and the greatest common multiple of 9 and 10 is infinite. The first 5 common multiples of 9 and 10 are 90, 180, 270, 360 and 450.
