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]).
35,70,105.140
Well, isn't that just a happy little question! Common multiples are like friends that these numbers can all share. If we look at the multiples of 2, 5, and 7, we can find numbers like 70, 140, 210, and so on, where they all come together and have a good time. Just remember, there's no mistakes in math, just happy little numbers!

Since all 3 are prime numbers LCM = 3 * 5 * 7 = 105 All multiples of 105 are multiples of 3, 5 and 7
Common multiples of 7 and 5 include 35, 70, 140, etc.

There is an infinite number of common multiples for these numbers!
35 and 70 both have 7 and 5 as prime factors
Since 14 is a multiple of 7, all of its multiples are common.

Since all 3 are prime numbers LCM = 3 * 5 * 7 = 105 All multiples of 105 are multiples of 3, 5 and 7
42 is the LCM of 3, 6 and 7. All multiples of 42 are multiples of 3, 6 and 7
