First three common multiples of 5 and 6 are 30, 60 and 90.
Multiples of 6 are numbers in the 6 times table. So the first 5 multiples of 6 are 6, 12, 18, 24 and 30.
The first 6 multiples of 5 are: 5, 10, 15, 20, 25, and 30.
The first 5 multiples of 3 are as follows: 3, 6, 9, 12, 15
The lowest common multiple of 5 and 6 is 30, as it is the first number that appears in both the 5 times table (multiples of 5) and the 6 times table (multiples of 6).
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.
The first 6 multiples of 1 are: 1, 2, 3, 4, 5, and 6.
The first five multiples of 6 are 6, 12, 18, 24 and 30. For them to be common, they need to be compared to another set of multiples.
6,12,18,24,30
90
5 + 10+15+20=50 ans
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.
