210, 420, 630, 840, 1050
Five common multiples. Only one can be least.
What are the first three common multiples of four and five
30, 60, 90, 120, 150
20. lol :-)
the first five common
The first five multiples of 4 are 4, 8, 12, 16 and 20. For them to be common, they need to be compared to another set of multiples.
The first five multiples of 15 are 15, 30, 45, 60, 75. For them to be common, they need to be compared to another set of multiples.
They are the first five multiples of their lowest common multiple: 140, 280, 420, 560, 700.
The first five common multiples of seven and twenty are: 140, 280, 420, 560, 700.
Any and all common multiples of 8 and 11 will be divisible by the least common multiple of 8 and 11, which is 88. Therefore, the first five common multiples of 8 and 11 will be the first five multiples of 88. This gives 88, 176, 264, 352, and 440.88, 176, 264, 352, 440
The LCM is: 30
The common multiples of 5 and 8 are the multiples of their lowest common multiple; lcm(5, 8) = 40 → the first five common multiples of 5 and 8 are: 40, 80, 120, 160, 200.
The common multiples of any two (or more) numbers are multiples of their lowest common multiple (lcm). lcm(9, 11) = 99 → first five common multiples are: 99, 198, 297, 396, 495
