14, 28, 42, 56, 70.
The first 3 multiples of 7 are: 7, 14, and 21.
The multiples of 3 up to 30 are: 3,6,9,12,15,18,21,24,27,30.The multiples of 5 up to 30 are: 5,10,15,20,25,30.The only common multiples are 15 and 30.The LCM is: 30
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, ...
There are infinitely many of them so it is impossible to give a full answer.I suggest you use your calculator and work out14*1,14*2,14*3,etc until you have as many multiples as you want.14, 28, 42 and so on.
No. Such a list would be infinitely long.
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.
Common multiples of 3 and 14 include 42, 84, and 126, among an infinite number of others.
14, 28, 42, 56, 70.
7, 14, 21, 28
Any multiple of 14.They are members of the infinite set of numbers of the form 14*k where k is an integer. Since the set is infinite, it is not possible to list them.
3, 9, 15
The first 3 multiples of 7 are: 7, 14, and 21.
Multiples of 7 include 7, 14, 21, 28 and so on. For them to be common, they need to be compared to another set of multiples.
28 itself and multiples of 28
There are an infinite number of multiples of any number. Therefore, it is impossible to list all the multiples of 3 and 4. A list of the first 10 multiples: Multiples of 3: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30 Multiples of 4: 4, 8, 12, 16, 20, 24, 28, 32, 36, 40
2 and 4 are common multiples of the numbers 14 and 20
