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 27,559,295, 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 | 27,559,295 | |
| -1 | -27,559,295 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 27,559,295.
Example:
1 x 27,559,295 = 27,559,295
and
-1 x -27,559,295 = 27,559,295
Notice both answers equal 27,559,295
With that explanation out of the way, let's continue. Next, we take the number 27,559,295 and divide it by 2:
27,559,295 ÷ 2 = 13,779,647.5
If the quotient is a whole number, then 2 and 13,779,647.5 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 | 27,559,295 | |
| -1 | -27,559,295 |
Now, we try dividing 27,559,295 by 3:
27,559,295 ÷ 3 = 9,186,431.6667
If the quotient is a whole number, then 3 and 9,186,431.6667 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 | 27,559,295 | |
| -1 | -27,559,295 |
Let's try dividing by 4:
27,559,295 ÷ 4 = 6,889,823.75
If the quotient is a whole number, then 4 and 6,889,823.75 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 | 27,559,295 | |
| -1 | 27,559,295 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 89 | 445 | 1,513 | 3,643 | 7,565 | 18,215 | 61,931 | 309,655 | 324,227 | 1,621,135 | 5,511,859 | 27,559,295 |
| -1 | -5 | -17 | -85 | -89 | -445 | -1,513 | -3,643 | -7,565 | -18,215 | -61,931 | -309,655 | -324,227 | -1,621,135 | -5,511,859 | -27,559,295 |
