81, 162, 243 and so on.
1, 3 and 9 are common factors of 27, 45 and 81. 27, 45 and 81 are multiples of 1, 3 and 9.
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 include any multiple of 405.
They are all multiples of 9. Their common multiples are 405, 810, 1215 and so on.
GCD: 27 LCM: 162 All common factors of 81 and 54 are all multiples of their LCM.
Every multiple of 81 is also a multiple of 27.
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.
1,3,69,0 The above are FACTORS. Here are 3 multiples of 27: 27, 54, 81
This cannot be answered because the common multiples of any two or more numbers are infinite.
The Lcm of 27 and 81 is 81, and the GCF of 27 and 81 is 27
some are 27, 54, 81, 108, and 135....
27 54 81 108
