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 403,044,031, 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 | 403,044,031 | |
| -1 | -403,044,031 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 403,044,031.
Example:
1 x 403,044,031 = 403,044,031
and
-1 x -403,044,031 = 403,044,031
Notice both answers equal 403,044,031
With that explanation out of the way, let's continue. Next, we take the number 403,044,031 and divide it by 2:
403,044,031 ÷ 2 = 201,522,015.5
If the quotient is a whole number, then 2 and 201,522,015.5 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 | 403,044,031 | |
| -1 | -403,044,031 |
Now, we try dividing 403,044,031 by 3:
403,044,031 ÷ 3 = 134,348,010.3333
If the quotient is a whole number, then 3 and 134,348,010.3333 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 | 403,044,031 | |
| -1 | -403,044,031 |
Let's try dividing by 4:
403,044,031 ÷ 4 = 100,761,007.75
If the quotient is a whole number, then 4 and 100,761,007.75 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 | 403,044,031 | |
| -1 | 403,044,031 |
If you did it right, you will end up with this table:
| 1 | 13 | 43 | 373 | 559 | 1,933 | 4,849 | 16,039 | 25,129 | 83,119 | 208,507 | 721,009 | 1,080,547 | 9,373,117 | 31,003,387 | 403,044,031 |
| -1 | -13 | -43 | -373 | -559 | -1,933 | -4,849 | -16,039 | -25,129 | -83,119 | -208,507 | -721,009 | -1,080,547 | -9,373,117 | -31,003,387 | -403,044,031 |
