700 and 7000 are two examples.
The least common multiples of 7 and 14 are 14,28 and 42>
There is an infinite number of common multiples for 5 6 and 7. A common multiple of any two or more numbers is any number into which each of two or more numbers can be divided evenly (zero remainder). However, the least or lowest common multiple (LCM) of 5 6 and 7 is 210.
Here are some common multiples of 12 and 7 84, 168, 1008 and 12096.
The common multiples of 5 and 6 are the multiples of their lowest common multiple (which is 30), so there are infinitely many common multiples of 5 and 6. The first five are: 30, 60, 90, 120, 150.
There is an infinite number of common multiples for these numbers!
35,70,105.140
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 least common multiple of the numbers 12, 5 and 7 is 420.
Any multiple of 105.
315
The LCM of (5, 6, 7) is 210.
35 and 70 both have 7 and 5 as prime factors
Any multiple of 420
