18, 36, 54 and so on.
18, 36, 54
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
24 = 3 x 2 x 2 x 29 = 3 x 3prime common multiples = 3common multiples = 1,3
Because 9 is a multiple of 3, the common multiples of 3 and 9 are the multiples of 9. The first 10 common multiples of 3 and 9 are 9, 18, 27, 36, 45, 54, 63, 72, 81, and 90.
18.
lowest common multiple is 18
18, 36, 54
18, 36, 54
18, 36, 54 and so on.
The least common multiples of the number 6 and 9 is 3.
Any multiple of 9 is a common multiple of 3 and 9.
The common multiples of an set of numbers are the multiples of their lowest common multiple. lcm(7, 8, 9) = 504 → the first 3 common multiples of 7, 8, 9 are 504, 1008, 1512.
1, 3 and 9 are common factors of 27, 45 and 81. 27, 45 and 81 are multiples of 1, 3 and 9.
