There can only be one greatest and the greatest common multiple of 9 and 10 is infinite. The first 5 common multiples of 9 and 10 are 90, 180, 270, 360 and 450.
The first 5 common multiples are the first 5 multiples of their lowest common multiple (LCM) LCM(9, 10) = 90 → first 5 common multiples are 90, 180, 270, 360, 450.
10, 20, 30 The common multiples of 5 and 10 are multiples of their lowest common multiple. The lcm of 5 and 10, is 10. Thus the first three common multiples are 10, 20, 30.
10 is.
10
It is: 10
It is: 2
All the common multiples of a set of numbers are the multiples of their lowest common multiple: lcm(5, 8, 10) = 40 → first three common multiples are 40, 80, 120
They are 10 and 20
The first multiple of any number is the number itself. For it to be common, it needs to be compared to another set of multiples.
The GCF is 5.
The GCF is 5.
Multiples of 5 include 5, 10 and 15. For them to be common, they need to be compared to another set of multiples.
