30, 60, 90, 120, 150
The common multiples of 5 and 6 are the multiples of their lowest common multiple (which is 30), so there are infinitely many common multiples of 5 and 6. The first five are: 30, 60, 90, 120, 150.
6, 12, 18, 24, 30, 36, 42, 48, 54, 60, 66
6, 12, 18, 24, 30
6+12+18+24+30=90
The first five nonzero multiples of 6 are 6, 12, 18, 24 and 30.
5, 10, 15, 20, 25, 30, 35, 40.
The first 4 multiples of 10 are: 10, 20, 30, and 40.
The first five multiples of 10 are 10,20,30,40,50.... 1 * 10 = 10 2 * 10 = 20 3 * 10 = 30 4 * 10 = 40 5 * 10 = 50

30, 60, 90, 120, 150, 180, 210, 240, 270, 300
The first 10 multiples of 3 are: 3, 6, 9, 12, 15, 18, 21, 24, 27, and 30.
5, 10, 15, 20, 25, 30
First three common multiples of 5 and 6 are 30, 60 and 90.
30, 60, 90, 120, 150
Since the GCF of 5 and 6 is 1, their LCM is their product. The first five multiples of 30 are 30, 60, 90, 120, 150
