There are four multiples of 11 between 1 and 50 (2-49): 11, 22, 33, 44.
11 of them.
There are four multiples of 12 between 150 and 200: 156, 168, 180, 192
110, 120, 130, 140. (BETWEEN does not include the 100 and 150.)
There are 50 multiples of three that fall between and one and 150.
what are the common multiples of 7 and 11 between 1 and 100
12 of them.
6 of them.
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.
The first 11 multiples of 15 are: 15, 30, 45, 60, 75, 90, 105, 120, 135, 150, 165.
81 and 135
15, 30, 45, 60, 75, 90, 105, 120, 135, 150, 165
77, 154, 231, 308.... ( So on) Basically the multiples that are common between 7 and 11 are multiples of 77.
