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 10,870,327, 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 | 10,870,327 | |
| -1 | -10,870,327 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,870,327.
Example:
1 x 10,870,327 = 10,870,327
and
-1 x -10,870,327 = 10,870,327
Notice both answers equal 10,870,327
With that explanation out of the way, let's continue. Next, we take the number 10,870,327 and divide it by 2:
10,870,327 ÷ 2 = 5,435,163.5
If the quotient is a whole number, then 2 and 5,435,163.5 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 | 10,870,327 | |
| -1 | -10,870,327 |
Now, we try dividing 10,870,327 by 3:
10,870,327 ÷ 3 = 3,623,442.3333
If the quotient is a whole number, then 3 and 3,623,442.3333 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 | 10,870,327 | |
| -1 | -10,870,327 |
Let's try dividing by 4:
10,870,327 ÷ 4 = 2,717,581.75
If the quotient is a whole number, then 4 and 2,717,581.75 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 | 10,870,327 | |
| -1 | 10,870,327 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 101 | 221 | 487 | 1,313 | 1,717 | 6,331 | 8,279 | 22,321 | 49,187 | 107,627 | 639,431 | 836,179 | 10,870,327 |
| -1 | -13 | -17 | -101 | -221 | -487 | -1,313 | -1,717 | -6,331 | -8,279 | -22,321 | -49,187 | -107,627 | -639,431 | -836,179 | -10,870,327 |
