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 10,571,687, 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 | 10,571,687 | |
| -1 | -10,571,687 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,571,687.
Example:
1 x 10,571,687 = 10,571,687
and
-1 x -10,571,687 = 10,571,687
Notice both answers equal 10,571,687
With that explanation out of the way, let's continue. Next, we take the number 10,571,687 and divide it by 2:
10,571,687 ÷ 2 = 5,285,843.5
If the quotient is a whole number, then 2 and 5,285,843.5 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 | 10,571,687 | |
| -1 | -10,571,687 |
Now, we try dividing 10,571,687 by 3:
10,571,687 ÷ 3 = 3,523,895.6667
If the quotient is a whole number, then 3 and 3,523,895.6667 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 | 10,571,687 | |
| -1 | -10,571,687 |
Let's try dividing by 4:
10,571,687 ÷ 4 = 2,642,921.75
If the quotient is a whole number, then 4 and 2,642,921.75 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 | 10,571,687 | |
| -1 | 10,571,687 |
If you did it right, you will end up with this table:
| 1 | 7 | 71 | 89 | 239 | 497 | 623 | 1,673 | 6,319 | 16,969 | 21,271 | 44,233 | 118,783 | 148,897 | 1,510,241 | 10,571,687 |
| -1 | -7 | -71 | -89 | -239 | -497 | -623 | -1,673 | -6,319 | -16,969 | -21,271 | -44,233 | -118,783 | -148,897 | -1,510,241 | -10,571,687 |
