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 8,979,859, 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 | 8,979,859 | |
| -1 | -8,979,859 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,979,859.
Example:
1 x 8,979,859 = 8,979,859
and
-1 x -8,979,859 = 8,979,859
Notice both answers equal 8,979,859
With that explanation out of the way, let's continue. Next, we take the number 8,979,859 and divide it by 2:
8,979,859 ÷ 2 = 4,489,929.5
If the quotient is a whole number, then 2 and 4,489,929.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 8,979,859 | |
| -1 | -8,979,859 |
Now, we try dividing 8,979,859 by 3:
8,979,859 ÷ 3 = 2,993,286.3333
If the quotient is a whole number, then 3 and 2,993,286.3333 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 8,979,859 | |
| -1 | -8,979,859 |
Let's try dividing by 4:
8,979,859 ÷ 4 = 2,244,964.75
If the quotient is a whole number, then 4 and 2,244,964.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 8,979,859 | |
| -1 | 8,979,859 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 59 | 119 | 413 | 1,003 | 1,279 | 7,021 | 8,953 | 21,743 | 75,461 | 152,201 | 528,227 | 1,282,837 | 8,979,859 |
| -1 | -7 | -17 | -59 | -119 | -413 | -1,003 | -1,279 | -7,021 | -8,953 | -21,743 | -75,461 | -152,201 | -528,227 | -1,282,837 | -8,979,859 |
