They are 84, 84084 and 8484840084
Common multiples of 7 and 4 include any multiple of 28.
Oh, isn't that a happy little question! When we talk about multiples, we're looking at numbers that both 4 and 7 can divide into evenly. So, if we list out the multiples of 4 (4, 8, 12, 16, 20, 24...) and the multiples of 7 (7, 14, 21, 28...), we can find their common multiples by seeing where these lists intersect. The common multiples of 4 and 7 would be numbers like 28, 56, 84, and so on. Just like painting, finding common multiples is all about patience and a gentle touch!
Since 4 divides 12, they are the first 7 multiples of 12.
There are not just three common multiples, but infinitely many. They are 168 and it multiples, so 1680 and 16800.

To find the common multiples of 2, 3, and 7, we first list the multiples of each number: Multiples of 2: 2, 4, 6, 8, 10, 12, ... Multiples of 3: 3, 6, 9, 12, 15, 18, ... Multiples of 7: 7, 14, 21, 28, 35, ... The first common multiple of 2, 3, and 7 is 6, as it is the smallest number that is a multiple of all three numbers. The second common multiple is 12, as it is the next number that is a multiple of all three numbers.
