Positive:
1 x 9842 x 4923 x 3284 x 2466 x 1648 x 12312 x 8224 x 41
Negative:
-1 x -984-2 x -492-3 x -328-4 x -246-6 x -164-8 x -123-12 x -82-24 x -41
Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 984, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 984 | |
| -1 | -984 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 984.
Example:
1 x 984 = 984
and
-1 x -984 = 984
Notice both answers equal 984
With that explanation out of the way, let's continue. Next, we take the number 984 and divide it by 2:
984 ÷ 2 = 492
If the quotient is a whole number, then 2 and 492 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!
Here is what our table should look like at this step:
| 1 | 2 | 492 | 984 | |
| -1 | -2 | -492 | -984 |
Now, we try dividing 984 by 3:
984 ÷ 3 = 328
If the quotient is a whole number, then 3 and 328 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!
Here is what our table should look like at this step:
| 1 | 2 | 3 | 328 | 492 | 984 | |
| -1 | -2 | -3 | -328 | -492 | -984 |
Let's try dividing by 4:
984 ÷ 4 = 246
If the quotient is a whole number, then 4 and 246 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!
Here is what our table should look like at this step:
| 1 | 2 | 3 | 4 | 246 | 328 | 492 | 984 | |
| -1 | -2 | -3 | -4 | -246 | -328 | -492 | 984 |
If you did it right, you will end up with this table:
| 1 | 2 | 3 | 4 | 6 | 8 | 12 | 24 | 41 | 82 | 123 | 164 | 246 | 328 | 492 | 984 |
| -1 | -2 | -3 | -4 | -6 | -8 | -12 | -24 | -41 | -82 | -123 | -164 | -246 | -328 | -492 | -984 |
