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 404,252,251, 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 | 404,252,251 | |
| -1 | -404,252,251 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 404,252,251.
Example:
1 x 404,252,251 = 404,252,251
and
-1 x -404,252,251 = 404,252,251
Notice both answers equal 404,252,251
With that explanation out of the way, let's continue. Next, we take the number 404,252,251 and divide it by 2:
404,252,251 ÷ 2 = 202,126,125.5
If the quotient is a whole number, then 2 and 202,126,125.5 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 | 404,252,251 | |
| -1 | -404,252,251 |
Now, we try dividing 404,252,251 by 3:
404,252,251 ÷ 3 = 134,750,750.3333
If the quotient is a whole number, then 3 and 134,750,750.3333 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 | 404,252,251 | |
| -1 | -404,252,251 |
Let's try dividing by 4:
404,252,251 ÷ 4 = 101,063,062.75
If the quotient is a whole number, then 4 and 101,063,062.75 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 | 404,252,251 | |
| -1 | 404,252,251 |
If you did it right, you will end up with this table:
| 1 | 13 | 41 | 533 | 593 | 1,279 | 7,709 | 16,627 | 24,313 | 52,439 | 316,069 | 681,707 | 758,447 | 9,859,811 | 31,096,327 | 404,252,251 |
| -1 | -13 | -41 | -533 | -593 | -1,279 | -7,709 | -16,627 | -24,313 | -52,439 | -316,069 | -681,707 | -758,447 | -9,859,811 | -31,096,327 | -404,252,251 |
