The least common multiple of 7 and 20 is 140. The next 4 common multiples come from 140 x 2, 140 x 3 etc...
The first five common multiples of seven and twenty are: 140, 280, 420, 560, 700.
What are the first three common multiples of four and five
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.
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 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 first five common multiples of seven and twenty are: 140, 280, 420, 560, 700.
What are the first three common multiples of four and five

the first five common
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.
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.
They are the first five multiples of their lowest common multiple: 140, 280, 420, 560, 700.
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
90, 180, 270, 360, 450 28, 56, 84, 112, 140
The first five multiples of 5 are 5, 10, 15, 20 and 25. For them to be common, they need to be compared to another set of multiples.
