90, 180, 270
First three common multiples of 5 and 6 are 30, 60 and 90.
The first 5 multiples of 6 are: 6, 12, 18, 24, and 30.The first 5 multiples of 9 are: 9, 18, 27, 36, and 45.
To find the common multiples of 6, 10, and 15, we first need to list the multiples of each number. The multiples of 6 are 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, etc. The multiples of 10 are 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, etc. The multiples of 15 are 15, 30, 45, 60, 75, 90, 105, 120, 135, 150, etc. The first three common multiples of 6, 10, and 15 are 30, 60, and 90.
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
