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 27,558,965, 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 | 27,558,965 | |
| -1 | -27,558,965 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 27,558,965.
Example:
1 x 27,558,965 = 27,558,965
and
-1 x -27,558,965 = 27,558,965
Notice both answers equal 27,558,965
With that explanation out of the way, let's continue. Next, we take the number 27,558,965 and divide it by 2:
27,558,965 ÷ 2 = 13,779,482.5
If the quotient is a whole number, then 2 and 13,779,482.5 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 | 27,558,965 | |
| -1 | -27,558,965 |
Now, we try dividing 27,558,965 by 3:
27,558,965 ÷ 3 = 9,186,321.6667
If the quotient is a whole number, then 3 and 9,186,321.6667 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 | 27,558,965 | |
| -1 | -27,558,965 |
Let's try dividing by 4:
27,558,965 ÷ 4 = 6,889,741.25
If the quotient is a whole number, then 4 and 6,889,741.25 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 | 27,558,965 | |
| -1 | 27,558,965 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 647 | 1,217 | 3,235 | 4,529 | 6,085 | 8,519 | 22,645 | 42,595 | 787,399 | 3,936,995 | 5,511,793 | 27,558,965 |
| -1 | -5 | -7 | -35 | -647 | -1,217 | -3,235 | -4,529 | -6,085 | -8,519 | -22,645 | -42,595 | -787,399 | -3,936,995 | -5,511,793 | -27,558,965 |
