there are 21 multiples.

There are infinitely many common multiples of 3, 5 and 7, each one 105 larger than the previous one. Or to put it another way: the common multiples of 3, 5 and 7 are the multiples of their lowest common multiple which is 105. ie their common multiples are all the multiples of 105, of which there is no end - there is an infinite number of multiples of 105 (or any other number [except zero]).
There is an infinite amount of common multiples starting with 77.

108
14 of them starting with 7 and ending with 98
14*7 = 98 < 100 < 105 = 15*7 and 21*7 = 147 < 150 < 154 = 22*7 So 21-14 = 7 multiples.
Multiples? There are an infinite amount. Factors on the other hand, there are: 1, 3, 7 and 21.
the set of multiples for 7 is infinite
15*6 = 90 and 15*7 = 105 so there are 6 multiples.
