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 31,202,327, 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 | 31,202,327 | |
| -1 | -31,202,327 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 31,202,327.
Example:
1 x 31,202,327 = 31,202,327
and
-1 x -31,202,327 = 31,202,327
Notice both answers equal 31,202,327
With that explanation out of the way, let's continue. Next, we take the number 31,202,327 and divide it by 2:
31,202,327 ÷ 2 = 15,601,163.5
If the quotient is a whole number, then 2 and 15,601,163.5 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 | 31,202,327 | |
| -1 | -31,202,327 |
Now, we try dividing 31,202,327 by 3:
31,202,327 ÷ 3 = 10,400,775.6667
If the quotient is a whole number, then 3 and 10,400,775.6667 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 | 31,202,327 | |
| -1 | -31,202,327 |
Let's try dividing by 4:
31,202,327 ÷ 4 = 7,800,581.75
If the quotient is a whole number, then 4 and 7,800,581.75 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 | 31,202,327 | |
| -1 | 31,202,327 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 59 | 221 | 767 | 1,003 | 2,393 | 13,039 | 31,109 | 40,681 | 141,187 | 528,853 | 1,835,431 | 2,400,179 | 31,202,327 |
| -1 | -13 | -17 | -59 | -221 | -767 | -1,003 | -2,393 | -13,039 | -31,109 | -40,681 | -141,187 | -528,853 | -1,835,431 | -2,400,179 | -31,202,327 |
