They are 11 times the numbers 1 to 9.
You seem to be unaware of the fact that you could have obtained the answer much more easily and quickly by using the calculator that comes as part of your computer.
Just 77.

What are the multiples of 7 and 11
what are the common multiples of 7 and 11 between 1 and 100
All the multiples of 11 up to 100 except 11 itself which is a prime number
Just 77.
11, 22, 33, 44, 55, 66, 77, 88, 99.
There are 11 multiples of 9 up to 100. 9 18 27 36 45 54 63 72 81 90 99
11, 22, 33, 44, 55, 66, 77, 88, 99
The COMMON multiples of 11 require at least one other number with which the multiple is COMMON. The COMMON multiples will be multiples of 11. The multiples of 11 between 1 and 100 are {11, 22, 33, 44, 55, 66, 77, 88, 99}, thus the COMMON multiples of 11 [with other numbers] wil be one, or more of this set.
I presume you mean what are all the multiples of 9 up to 100 (and not what are all the multiples of 9, 10, 11, ..., 100 of which there are infinitely many): 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, 99.
