They are 10 and 20
70 and 140
The two smallest multiples of 10 are 10 and 20. For them to be common, they would need to be compared to another set of multiples.
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.
170 because 17 is prime
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.
60 and 120 are the two lowest common multiples.
8 = 2310 = 2*512 = 22*3LCM = 3*5*8 = 120So the two first common multiples of 8, 10, and 12 are 120 and 240.
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
There are no multiples of ten.
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.
