The first three multiples of 3 are 3, 6, 9 The first three multiples of 9 are 9, 18, 27 As the lowest common multiples of 3 and 9 is 9, the common multiples of 3 and 9 are the multiples of 9, thus: The first three common multiples of 3 and 9 are 9, 18, 27
3+6+9...+45taking 3 common3(1+2+...+15) = 360
Sum of the first 15 positive integers is 15*(15+1)/2 = 120 Sum of the first 15 multiples of 8 is 8*120 = 960
The first ten multiples of 3 are 3, 6, 9, 12, 15, 18, 21, 24, 27, and 30. Multiples are numbers that can be divided evenly by a given number, in this case, 3. Each subsequent multiple is found by adding 3 to the previous multiple.
3, 6, 9 4, 8, 12 5, 10, 15 Common multiples include 60, 120, and 180.
The first 5 multiples of 3 are as follows: 3, 6, 9, 12, 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.
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 first 5 multiples of 5 are: 5, 10, 15, 20, 25 The first 5 multiples of 9 are: 9, 18, 27, 36, 45 The first 5 multiples of both 5 and 9 are: 45, 90, 135, 180, 225
3, 6, 9, 12, 15.
3, 6, 9, 12, 15.
3, 6, 9, 12, 15
45, 90, 135
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)
The first six multiples of 3 are 3, 6, 9, 12, 15, and 18.
3, 6, 9, 12, 15 The mean is 9.
90, 180 and 270
