42 is the LCM of 3, 6 and 7. All multiples of 42 are multiples of 3, 6 and 7
it's infinite
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]).
The common multiples of 3 and 7 are 21, 42, 63 and so on.
The common multiples of an set of numbers are the multiples of their lowest common multiple. lcm(7, 8, 9) = 504 → the first 3 common multiples of 7, 8, 9 are 504, 1008, 1512.

Since 14 is a multiple of 7, all of its multiples are common.
The common multiples of an set of numbers are the multiples of their lowest common multiple. lcm(7, 8, 9) = 504 → the first 3 common multiples of 7, 8, 9 are 504, 1008, 1512.
Odd multiples of 21.
Oh, dude, common multiples are just numbers that all three of these divas can divide into without any drama. So, for 2, 3, and 7, their common multiples would be like 42, 84, 126, and so on. It's like finding a party playlist that everyone can groove to without any complaints.
Multiples of 3 are 3, 6, 9 and so on. Multiples of 7 are 7, 14, 21 and so on. The common multiples of 3 and 7 include 21, 42, 63 and so on.
