All multiples of 90.
Yes it is... Multiples of 3 & 6 are 3, 6, 9, 12, 15 & 18
There is an infinite number of common multiples for 9 15 and 18. A common multiple of any two or more numbers is any number into which each of two or more numbers can be divided evenly (zero remainder). However, the least or lowest common multiple (LCM) of 9 15 and 18 is 90.
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.
18.
The set of multiples of 18.
Multiples of 3 include 3, 6, 9, 12, 15, 18 and so on. For them to be common, they need to be compared to another set of factors.
Multiples are just numbers that can be multiplied together to find the given number. So: Multiples of 9: 1,3,9 Multiples of 18: 1,2,3,6,9,18 Common Multiples of 9 & 18: 1,3,9
18
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 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
18, 36, 54, ...
it is 18. 18 is a multiple of all three numbers. multiples of 3: 3,6,9,12,15,18... multiples of 6: 6,12,18... multiples of 9: 9, 18...18
