Common multiples of 7 and 4 include any multiple of 28.
28, 56
4 of them.
To find a common multiple for 2, 4, and 7 with a digit sum of 11, we first need to find the multiples of each number. The multiples of 2 are 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, and so on. The multiples of 4 are 4, 8, 12, 16, 20, and so on. The multiples of 7 are 7, 14, 21, 28, 35, and so on. By examining the lists, we find that the number 28 is a common multiple for 2, 4, and 7 with a digit sum of 11.
I don't know 2, but 4x7=28, and that is a common factor.
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!
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.
Since 4 divides 12, they are the first 7 multiples of 12.
The common multiples of 2 and 7 are 14, 28, 42, 56, 70, 84, 98, and so on.
Common multiples of 2, 3, and 7 are numbers that are divisible by all three numbers. To find the common multiples, we first list the multiples of each number: multiples of 2 are 2, 4, 6, 8, 10, multiples of 3 are 3, 6, 9, 12, 15, and multiples of 7 are 7, 14, 21, 28. The common multiples of 2, 3, and 7 are numbers that appear in all three lists, which in this case are 42, 84, 126, etc.
