Write the multiple of 5 and 8

5 = 5, 10, 15, 20, 25, 30, 35, **40**,.....

8 = 8, 16, 24, 32, **40**, 48, 53,.....

We can observe that **40 **is least common multiple in both. So LCM is **40**

All you have to do is list the multiplies of both of the numbers and look for the common number. (as Deepak has demonstrated)

The LCM for 5/8 is 40.
