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.
what are the common multiples of 7 and 11 between 1 and 100
77
77 is the only common multiple of 7 and 77 between 1 and 100.
Just 77.
The common multiples of 4 and 11 are 44 and 88.
77.
44 and 88 are the only common multiples of 4 and 11 that are less than 100
The multiples of 11 in that range are 11, 22, 33, 44, 55, 66, 77, 88, 99. For them to be common, they would have to be compared to another set of multiples.
