My thinking is 36,72,108
lcm(4, 9) = 36 → the two least common multiples (ie the first two common multiples) of 4 and 9 are 36 and 72.
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 three multiples of 9 are 9, 18 and 27. For them to be common, they need to be compared to another set of factors.
The first 3 multiples of 4 are: 4, 8, and 12.The first 3 multiples of 9 are: 9, 18, and 27.
The common multiples of any two (or more) numbers are multiples of their lowest common multiple (lcm). lcm(9, 11) = 99 → first five common multiples are: 99, 198, 297, 396, 495
They are the first three multiples of their lowest common multiple: 36, 72, 108.
lcm(4, 9) = 36 → the two least common multiples (ie the first two common multiples) of 4 and 9 are 36 and 72.
Common multiples of 7 and 4 include any multiple of 28.
180 is the first one.
36, 72.
To find a number that is not a common multiple of 4 and 9, we need to consider the multiples of each number. The multiples of 4 are 4, 8, 12, 16, 20, 24, ... and the multiples of 9 are 9, 18, 27, 36, 45, ... The first number in the list of multiples of 4 that is not a multiple of 9 is 4. Therefore, 4 is a number that is not a common multiple of 4 and 9.
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
36, 72, 108
36, 72 and 108
18, 36, 54, 72
36, 72, and 108 are.
36, 72, 108
