There are an infinite number of them.
They include 28, 56, 476, and 532 .
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.
I don't know 2, but 4x7=28, and that is a common factor.
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.
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
