Common multiples of 3 and 14 include 42, 84, and 126, among an infinite number of others.
2 and 4 are common multiples of the numbers 14 and 20
42
As 84 = 14 x 6: All the factors of 14 are common to both, ie the common factors of 14 and 84 are: 1, 2, 7, 14; All the multiples of 84 are common to both 14 and 84, ie the common multiples of 14 and 84 are: 84, 168, 252, 336, 420, 504, 588, 672, 756, 840, ...
70, 140, 210
The common multiples of 14 and 35 are numbers that are divisible by both 14 and 35. To find the common multiples, we first list the multiples of each number. The multiples of 14 are 14, 28, 42, 56, 70, etc., and the multiples of 35 are 35, 70, 105, 140, etc. The common multiples of 14 and 35 are numbers that appear in both lists, such as 70.
Since 14 is a multiple of 7, all of its multiples are common.
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.
14 = 2 X 7 42 = 2 X 3 X 7 So 2 & 7 are common to both multiples / NB '3' is NOT a common multiple.
126, 252, 378
The least common multiples of 7 and 14 are 14,28 and 42>
14
The first 3 multiples of 7 are: 7, 14, and 21.The first 3 multiples of 14 are: 14, 28, and 42.
