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 10,876,073, 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 | 10,876,073 | |
| -1 | -10,876,073 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,876,073.
Example:
1 x 10,876,073 = 10,876,073
and
-1 x -10,876,073 = 10,876,073
Notice both answers equal 10,876,073
With that explanation out of the way, let's continue. Next, we take the number 10,876,073 and divide it by 2:
10,876,073 ÷ 2 = 5,438,036.5
If the quotient is a whole number, then 2 and 5,438,036.5 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 | 10,876,073 | |
| -1 | -10,876,073 |
Now, we try dividing 10,876,073 by 3:
10,876,073 ÷ 3 = 3,625,357.6667
If the quotient is a whole number, then 3 and 3,625,357.6667 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 | 10,876,073 | |
| -1 | -10,876,073 |
Let's try dividing by 4:
10,876,073 ÷ 4 = 2,719,018.25
If the quotient is a whole number, then 4 and 2,719,018.25 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 | 10,876,073 | |
| -1 | 10,876,073 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 29 | 221 | 377 | 493 | 1,697 | 6,409 | 22,061 | 28,849 | 49,213 | 375,037 | 639,769 | 836,621 | 10,876,073 |
| -1 | -13 | -17 | -29 | -221 | -377 | -493 | -1,697 | -6,409 | -22,061 | -28,849 | -49,213 | -375,037 | -639,769 | -836,621 | -10,876,073 |
