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 5,605,327, 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 | 5,605,327 | |
| -1 | -5,605,327 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,605,327.
Example:
1 x 5,605,327 = 5,605,327
and
-1 x -5,605,327 = 5,605,327
Notice both answers equal 5,605,327
With that explanation out of the way, let's continue. Next, we take the number 5,605,327 and divide it by 2:
5,605,327 ÷ 2 = 2,802,663.5
If the quotient is a whole number, then 2 and 2,802,663.5 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 | 5,605,327 | |
| -1 | -5,605,327 |
Now, we try dividing 5,605,327 by 3:
5,605,327 ÷ 3 = 1,868,442.3333
If the quotient is a whole number, then 3 and 1,868,442.3333 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 | 5,605,327 | |
| -1 | -5,605,327 |
Let's try dividing by 4:
5,605,327 ÷ 4 = 1,401,331.75
If the quotient is a whole number, then 4 and 1,401,331.75 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 | 5,605,327 | |
| -1 | 5,605,327 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 31 | 91 | 217 | 403 | 1,987 | 2,821 | 13,909 | 25,831 | 61,597 | 180,817 | 431,179 | 800,761 | 5,605,327 |
| -1 | -7 | -13 | -31 | -91 | -217 | -403 | -1,987 | -2,821 | -13,909 | -25,831 | -61,597 | -180,817 | -431,179 | -800,761 | -5,605,327 |
