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
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.
Common multiples of 14 and 35 include 70, 140 and 210
The least common multiples of 7 and 14 are 14,28 and 42>
126, 252, 378
14
The first 3 multiples of 7 are: 7, 14, and 21.The first 3 multiples of 14 are: 14, 28, and 42.
