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 27,659,387, 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 | 27,659,387 | |
| -1 | -27,659,387 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 27,659,387.
Example:
1 x 27,659,387 = 27,659,387
and
-1 x -27,659,387 = 27,659,387
Notice both answers equal 27,659,387
With that explanation out of the way, let's continue. Next, we take the number 27,659,387 and divide it by 2:
27,659,387 ÷ 2 = 13,829,693.5
If the quotient is a whole number, then 2 and 13,829,693.5 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 | 27,659,387 | |
| -1 | -27,659,387 |
Now, we try dividing 27,659,387 by 3:
27,659,387 ÷ 3 = 9,219,795.6667
If the quotient is a whole number, then 3 and 9,219,795.6667 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 | 27,659,387 | |
| -1 | -27,659,387 |
Let's try dividing by 4:
27,659,387 ÷ 4 = 6,914,846.75
If the quotient is a whole number, then 4 and 6,914,846.75 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 | 27,659,387 | |
| -1 | 27,659,387 |
If you did it right, you will end up with this table:
| 1 | 7 | 37 | 259 | 269 | 397 | 1,883 | 2,779 | 9,953 | 14,689 | 69,671 | 102,823 | 106,793 | 747,551 | 3,951,341 | 27,659,387 |
| -1 | -7 | -37 | -259 | -269 | -397 | -1,883 | -2,779 | -9,953 | -14,689 | -69,671 | -102,823 | -106,793 | -747,551 | -3,951,341 | -27,659,387 |
