There are 75 multiples of 12 between 100 and 1000.
Smallest multiple of 7 greater than 100 is 15 Largest multiple of 7 less than 1000 is 142 So number of multiples of 7 = 142 - 15 + 1 = 128
There are fourteen multiples of seven that are under 100.
The common multiples of a number with itself are the multiples of that number. Thus all multiples of A between 1 and 100 are the common multiples of A and A between 1 and 100.
