Since all 3 are prime numbers LCM = 3 * 5 * 7 = 105 All multiples of 105 are multiples of 3, 5 and 7
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 3,4, and 10 would be all the multiples of 60. 60, 120, 180, 240... all the way to 6000.
All multiples of their lowest common multiple: lcm(3, 5, 7) = 105 → the numbers less than 400 with 3, 5, 7 as factors are: 105, 210, 315.
They are: 3*5*7 = 105

Using digital roots (adding all the digits in a number up until you get a single digit) we can see that: 105: 1+0+5 = 6 63: 6+3 = 9 If both digital roots equal 3,6,and/or 9 then the LCM is always 3. The Normal Way: A few Multiples of 105: 105 / 5 = 21 21 / 7 = 3 3,5,7,21,105 A few Multiples of 63: 63 / 3 = 21 21 / 7 = 3 3,7,21,63 So as you can see, the LCM is 3.
