40, 80, 120, 160, 200, 240, 280, 320, 360, 400.
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.
10, 20, 30.
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!
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.
20 30 40
10, 20, 30.
