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.
21, 42, 63 and so on.
Any multiple of 105.
the first three common multiples of 7, 20, and 35 are 140, 280, and 420
The common factors are 1 and 7. (7 = 1 x 7 and 21 = 3 x 7) The only common prime factor is 7, which is also the largest common factor.
The common multiples of 3 and 7 are 21, 42, 63 and so on.
42 is the LCM of 3, 6 and 7. All multiples of 42 are multiples of 3, 6 and 7
Oh, dude, you want common multiples of 3 and 7 up to 100? Well, let me break it down for you. The common multiples of 3 and 7 are numbers that both 3 and 7 can divide evenly into. So, the common multiples of 3 and 7 up to 100 are 21, 42, 63, and 84. Like, that's it.
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.
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]).
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.

lcm(2, 7) = 14 → first 3 common multiples are: 14, 28, 42; lcm(2, 8) = 8 → first 3 common multiples are: 8, 16, 24; lcm(7, 8) = 56 → first 3 common multiples are: 56, 112, 168; lcm(2, 7, 8) = 56 → first 3 common multiples are: 56, 112, 168.
The common multiples of 3 and 7 are:21,42,63,84,105,126,147,168,189,210,etc.
