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 27,841,165, 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 | 27,841,165 | |
| -1 | -27,841,165 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 27,841,165.
Example:
1 x 27,841,165 = 27,841,165
and
-1 x -27,841,165 = 27,841,165
Notice both answers equal 27,841,165
With that explanation out of the way, let's continue. Next, we take the number 27,841,165 and divide it by 2:
27,841,165 ÷ 2 = 13,920,582.5
If the quotient is a whole number, then 2 and 13,920,582.5 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 | 27,841,165 | |
| -1 | -27,841,165 |
Now, we try dividing 27,841,165 by 3:
27,841,165 ÷ 3 = 9,280,388.3333
If the quotient is a whole number, then 3 and 9,280,388.3333 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 | 27,841,165 | |
| -1 | -27,841,165 |
Let's try dividing by 4:
27,841,165 ÷ 4 = 6,960,291.25
If the quotient is a whole number, then 4 and 6,960,291.25 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 | 27,841,165 | |
| -1 | 27,841,165 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 53 | 55 | 265 | 583 | 2,915 | 9,551 | 47,755 | 105,061 | 506,203 | 525,305 | 2,531,015 | 5,568,233 | 27,841,165 |
| -1 | -5 | -11 | -53 | -55 | -265 | -583 | -2,915 | -9,551 | -47,755 | -105,061 | -506,203 | -525,305 | -2,531,015 | -5,568,233 | -27,841,165 |
