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.
Multiples of 5 include 5, 10 and 15. For them to be common, they need to be compared to another set of multiples.
They are 10 and 20
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
The first five multiples of 5 are 5, 10, 15, 20 and 25. For them to be common, they need to be compared to another set of multiples.
Well, honey, common multiples of 5 and 10 are numbers that both 5 and 10 can divide evenly into. So, grab your calculator and start counting by 10s until you hit a number that is also divisible by 5. Spoiler alert: the first few common multiples are 10, 20, 30, 40... you get the idea. Happy math-ing!
10, 20, 30.
20 is the smallest common multiple of 4, 5, and 10, and thus the first. Thus, the first three common multiples of 4, 5, and 10 are 20, 40 and 60.
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.
10, 20, 30.
