They are 63 and 126
The first 2 multiples are 42,84.
Common multiples of 7 and 4 include any multiple of 28.
The lowest common multiple of the two numbers is 42. All multiples of 42 are common multiples of 6 and 7. So the common multiples of 6 and 7 are 42, 84, 126, 168, 210, 252, 294, 336, and so on.
The first common multiple of 3 4 5 and 7 is 420.
56, 112, 168
The first 2 multiples are 42,84.
42 and 84
The common multiples of an set of numbers are the multiples of their lowest common multiple. lcm(7, 8, 9) = 504 → the first 3 common multiples of 7, 8, 9 are 504, 1008, 1512.
Common multiples of 7 and 4 include any multiple of 28.
Since 4 divides 12, they are the first 7 multiples of 12.
lcm(2, 7) = 14 → first 3 common multiples are: 14, 28, 42; lcm(2, 8) = 8 → first 3 common multiples are: 8, 16, 24; lcm(7, 8) = 56 → first 3 common multiples are: 56, 112, 168; lcm(2, 7, 8) = 56 → first 3 common multiples are: 56, 112, 168.
The First common multiple of 6 and 7 is 42 and the next common multiple is 84.
