I don't know 2, but 4x7=28, and that is a common factor.
21 and 28
Common multiples of 7 and 4 include any multiple of 28.
The common multiples of 4 and 7 are numbers that are divisible by both 4 and 7. To find the common multiples, you can list out the multiples of each number and then identify the numbers that appear in both lists. The common multiples of 4 and 7 are 28, 56, 84, 112, and so on, as they are divisible by both 4 and 7.
20 just do 4 times whatever and 7 times whatever until you get a like answer :)
Since 4 divides 12, they are the first 7 multiples of 12.
There are an infinite number of them. They include 28, 56, 476, and 532 .
2,56,84
28 and 56
This cannot be answered because the common multiples of any two or more numbers are infinite.
42 and 84
700 and 7000 are two examples.
LCM(4, 11, 7) = 308
