There is an infinite number of common multiples for 27 and 111. 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).
Multiples of 27 include 27, 54, 81 and so on. For them to be common, they need to be compared to another set of multiples.
Common Multiples are multiples which are common to both numbers So Multiples of 9 are 9, 18, 27, 36 etc... Multiples of 27 are 27, 54, 81 etc... you can work out the least common multiple as 27 We can see that 9 is a factor of 27 so all multiples of 27 are a common multiple with 9. But as there is no upper limit we can not work out a greatest common multiple as they bigger they get the closer they get to infinity! You tend to work out Greatest Common Factor and Least Common Multiple with regards numbers.
The common multiples of 27 and 36 are 108, 216, 324 and so on.
the first two common multiples of 15,27 are 135,270
The common multiples of 15 and 27 are numbers that can be evenly divided by both 15 and 27.
