6+12+18+24+30=90
5 + 10+15+20=50 ans
30, 60, 90, 120, 150
1 x 6 = 62 x 6 = 12The sum of 12 + 6 = 18
6 + 12 + 18 + 24 + 30 + 36 = 126
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.
The first five nonzero multiples of 6 are 6, 12, 18, 24 and 30.
90
5 + 10+15+20=50 ans
It is: 6+12+18 = 36
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 sum of three consecutive multiples of 6 is 666, the multiples are 216, 222 and 228.
30, 60, 90, 120, 150
1 x 6 = 62 x 6 = 12The sum of 12 + 6 = 18
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.
0, 2, 4, 6, 8.0,2,4,6,8 are the first five multiples of 2
30,60,90,120,150
6 + 12 + 18 + 24 + 30 + 36 = 126
