Find the LCM for 3 and 8



Hi Michaela,
To find the LCM (lowest common multiple)
Choose the biggest number, which is 8
write down the multiples of 8
8,16,24,32,....
then look at them and find the smallest one that is also a multiple of 3
-----------------------------------
If this is a bit difficult, you could also write down the multiples of 3
3,6,9,12,15,18,21,24,27

The smallest number that is in both lists is the answer!
