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 404,631,359, 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 | 404,631,359 | |
| -1 | -404,631,359 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 404,631,359.
Example:
1 x 404,631,359 = 404,631,359
and
-1 x -404,631,359 = 404,631,359
Notice both answers equal 404,631,359
With that explanation out of the way, let's continue. Next, we take the number 404,631,359 and divide it by 2:
404,631,359 ÷ 2 = 202,315,679.5
If the quotient is a whole number, then 2 and 202,315,679.5 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 | 404,631,359 | |
| -1 | -404,631,359 |
Now, we try dividing 404,631,359 by 3:
404,631,359 ÷ 3 = 134,877,119.6667
If the quotient is a whole number, then 3 and 134,877,119.6667 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 | 404,631,359 | |
| -1 | -404,631,359 |
Let's try dividing by 4:
404,631,359 ÷ 4 = 101,157,839.75
If the quotient is a whole number, then 4 and 101,157,839.75 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 | 404,631,359 | |
| -1 | 404,631,359 |
If you did it right, you will end up with this table:
| 1 | 11 | 131 | 227 | 1,237 | 1,441 | 2,497 | 13,607 | 29,737 | 162,047 | 280,799 | 327,107 | 1,782,517 | 3,088,789 | 36,784,669 | 404,631,359 |
| -1 | -11 | -131 | -227 | -1,237 | -1,441 | -2,497 | -13,607 | -29,737 | -162,047 | -280,799 | -327,107 | -1,782,517 | -3,088,789 | -36,784,669 | -404,631,359 |
