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 10,876,585, 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 | 10,876,585 | |
| -1 | -10,876,585 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,876,585.
Example:
1 x 10,876,585 = 10,876,585
and
-1 x -10,876,585 = 10,876,585
Notice both answers equal 10,876,585
With that explanation out of the way, let's continue. Next, we take the number 10,876,585 and divide it by 2:
10,876,585 ÷ 2 = 5,438,292.5
If the quotient is a whole number, then 2 and 5,438,292.5 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 | 10,876,585 | |
| -1 | -10,876,585 |
Now, we try dividing 10,876,585 by 3:
10,876,585 ÷ 3 = 3,625,528.3333
If the quotient is a whole number, then 3 and 3,625,528.3333 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 | 10,876,585 | |
| -1 | -10,876,585 |
Let's try dividing by 4:
10,876,585 ÷ 4 = 2,719,146.25
If the quotient is a whole number, then 4 and 2,719,146.25 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 | 10,876,585 | |
| -1 | 10,876,585 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 271 | 349 | 1,355 | 1,745 | 6,233 | 8,027 | 31,165 | 40,135 | 94,579 | 472,895 | 2,175,317 | 10,876,585 |
| -1 | -5 | -23 | -115 | -271 | -349 | -1,355 | -1,745 | -6,233 | -8,027 | -31,165 | -40,135 | -94,579 | -472,895 | -2,175,317 | -10,876,585 |
