2 x 2 x 2 x 7
The LCM of the numbers 4, 7, and 8 is 56.
No. Just try it out with 2, or 4, negative numbers.
Negative numbers are numbers that go below.say you have 3 and take away 4 that would take you to negative 1 .
1 x 112, 2 x 56, 4 x 28, 7 x 16, 8 x 14 = 112 and 56 + 56 = 112
66
1 * 56 = 56 2 * 28 = 56 4 * 14 = 56 7 * 8 = 56 8 * 7 = 56 14 * 4 = 56 28 * 2 = 56 56 * 1 = 56

Oh, what a lovely little math puzzle we have here! Let's see, to find the 4 numbers that multiply together to make 56, we can start by thinking about factors of 56. How about 1, 2, 4, and 14? When you multiply these numbers together, you get 56. Isn't that just delightful? Remember, there are many ways to approach a problem, and it's all about enjoying the process of discovery.
In order to multiply two numbers together when one or more of them is negative, you start by multiplying them normally. In this case 4x7 = 28. The next step is to assess whether or not the answer is a negative or positive. If the two numbers being multiplied were the same (both negative or both positive) then the answer is positive. Otherwise, it is negative. In this case, we had -4 and -7 which are both negative, so the answer is positive 28. Thus the question can be rewritten as 2x28. This comes out as 56. Therefore 2 times negative 4 times negative 7 is 56.
1 x 56, 2 x 28, 4 x 14, 7 x 8
numbers -4 and 1 1 and -4 1 and -4
List numbers that multiply to make 28 and find their sums. Since negative times a negative is positive, list the negatives. -1, -28 = -29 -2, -14 = -15 -4, -7 = -11 Aha! -4 and -7 multiply to make 28 and add to -11; therefore, -4 and -7 are the two numbers.
2 x 2 x 2 x 7
You can make the two numbers 6 plus 4, because it's the same thing. So, 6 minus negative 4 is 10.
The LCM of the numbers 4, 7, and 8 is 56.
No. Just try it out with 2, or 4, negative numbers.
