Common multiples of 7 and 4 include any multiple of 28.
To find the common multiples of 2, 3, and 7, we first list the multiples of each number: Multiples of 2: 2, 4, 6, 8, 10, 12, ... Multiples of 3: 3, 6, 9, 12, 15, 18, ... Multiples of 7: 7, 14, 21, 28, 35, ... The first common multiple of 2, 3, and 7 is 6, as it is the smallest number that is a multiple of all three numbers. The second common multiple is 12, as it is the next number that is a multiple of all three numbers.
The first common multiple of 3 4 5 and 7 is 420.
56, 112, 168
The common multiples of 6, 7, and 8 are numbers that are divisible by all three of these numbers. To find the common multiples, we first list the multiples of each number: 6 (6, 12, 18, 24, 30, ...), 7 (7, 14, 21, 28, 35, ...), and 8 (8, 16, 24, 32, 40, ...). The common multiples of 6, 7, and 8 are the numbers that appear in all three lists, such as 24 and 48.
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.
To find the common multiples of 2, 3, and 7, we first list the multiples of each number: Multiples of 2: 2, 4, 6, 8, 10, 12, ... Multiples of 3: 3, 6, 9, 12, 15, 18, ... Multiples of 7: 7, 14, 21, 28, 35, ... The first common multiple of 2, 3, and 7 is 6, as it is the smallest number that is a multiple of all three numbers. The second common multiple is 12, as it is the next number that is a multiple of all three numbers.
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.
