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 39,614,869, 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 | 39,614,869 | |
| -1 | -39,614,869 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 39,614,869.
Example:
1 x 39,614,869 = 39,614,869
and
-1 x -39,614,869 = 39,614,869
Notice both answers equal 39,614,869
With that explanation out of the way, let's continue. Next, we take the number 39,614,869 and divide it by 2:
39,614,869 ÷ 2 = 19,807,434.5
If the quotient is a whole number, then 2 and 19,807,434.5 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 | 39,614,869 | |
| -1 | -39,614,869 |
Now, we try dividing 39,614,869 by 3:
39,614,869 ÷ 3 = 13,204,956.3333
If the quotient is a whole number, then 3 and 13,204,956.3333 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 | 39,614,869 | |
| -1 | -39,614,869 |
Let's try dividing by 4:
39,614,869 ÷ 4 = 9,903,717.25
If the quotient is a whole number, then 4 and 9,903,717.25 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 | 39,614,869 | |
| -1 | 39,614,869 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 217 | 311 | 587 | 2,177 | 4,109 | 9,641 | 18,197 | 67,487 | 127,379 | 182,557 | 1,277,899 | 5,659,267 | 39,614,869 |
| -1 | -7 | -31 | -217 | -311 | -587 | -2,177 | -4,109 | -9,641 | -18,197 | -67,487 | -127,379 | -182,557 | -1,277,899 | -5,659,267 | -39,614,869 |
