Any multiple of 105.
Any multiple of 105.
Multiples of 15 include 15, 30 and 45. For them to be common, they need to be compared to another set of multiples.
They are the six multiples of 15.
The multiples of 15 are 15, 30, 45, 60, 75 and so on. For them to be common, they need to be compared to another set of multiples.
Two common multiples of 21 and 15 are 105 and 315.
There are infinite common multiples for a set of numbers. So it is not possible to write down all the common multiples. Some common multiples of 15, 30 and 45 are 90, 180, 270, 360,... There is another way to find common multiples: Write the multiples of LCM(15, 30, 45). Actually the common multiples of a set of numbers are the multiples of their LCM. LCM of 15, 30 and 45 is 90. And the multiples of 90 are 90, 180, 270, 360, 450, 540,... which are the common multiples of 15, 30 and 45.
Since 14 is a multiple of 7, all of its multiples are common.

Multiples of 15 include 15, 30 and 45. For them to be common, they need to be compared to another set of multiples.
The least common multiples of 7 and 14 are 14,28 and 42>
There is an infinite number of common multiples for these numbers!
Multiples of 7 include 7, 14, 21, 28 and so on. For them to be common, they need to be compared to another set of multiples.
