18, 27, 36.
45 and 54 are the multiples of 9 between 40 and 60
Multiple is just a number that the number will go in to. Examples: Multiples of 3: 3, 6, 9, 12, 15, ... Multiples of 20: 20, 40, 60, 80, ... Not sure what your question is asking "between 200", but I hope my examples helped.
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.
3, 6, 9, 12, 15.
The odd numbers: 1, 3, 9, 15, 21 (that I know of, there are more but I'm not sure what they are.)
The lowest common multiple of 15, 9 and 3 is 45 but the individual multiples of 15, 9 and 3 can go on for evermore
3, 6, 9, 12, 15, 18
All multiples of 90.
They are all multiples of 3.
3, 9, 15, 21, 27
4 and 8 are multiples of 2. 6 and 9 are multiples of 3. 40 and 50 are multiples of 10.
Multiples of 3 are 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, and so on. Multiples of 5 are 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, adn so on. The common multiples of 3 and 5 are all of the multiples of 15, i.e. 15, 30, 45, 60, 75, 90, and so on.
