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
20 pinkgal333:20, 40, 60 are all common multiples.
20, 40, 60, 80 and so on.
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 is no upper limit to common multiples. LCM of 32 & 40 is 160...

Multiples of 10 include any number ending in zero. For them to be common, they need to be compared to another set of multiples.
20 pinkgal333:20, 40, 60 are all common multiples.
The Least Common Multiple (LCM) for 8 10 is 40.
Any multiple of 40.
They are 40 and 80
Least common multiple of 8 and 10 is 40 that's like this write down multiples of the whole number 8 first, they are 8,16,24,32,40,48,56,64,72,80,88 etc.. now write down multiples of the whole number 10,they are 10,20,30,40,50,60,70,80,90 etc...... as you can see 40 and 80 are common multiples in the series but 40 is the smallest one hence it is the LCM of 8 and 10
Multiples of 40 include 40, 80, 120 and so on. For them to be common, they need to be compared to another set of multiples.
