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 563,161,469, 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 | 563,161,469 | |
| -1 | -563,161,469 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 563,161,469.
Example:
1 x 563,161,469 = 563,161,469
and
-1 x -563,161,469 = 563,161,469
Notice both answers equal 563,161,469
With that explanation out of the way, let's continue. Next, we take the number 563,161,469 and divide it by 2:
563,161,469 ÷ 2 = 281,580,734.5
If the quotient is a whole number, then 2 and 281,580,734.5 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 | 563,161,469 | |
| -1 | -563,161,469 |
Now, we try dividing 563,161,469 by 3:
563,161,469 ÷ 3 = 187,720,489.6667
If the quotient is a whole number, then 3 and 187,720,489.6667 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 | 563,161,469 | |
| -1 | -563,161,469 |
Let's try dividing by 4:
563,161,469 ÷ 4 = 140,790,367.25
If the quotient is a whole number, then 4 and 140,790,367.25 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 | 563,161,469 | |
| -1 | 563,161,469 |
If you did it right, you will end up with this table:
| 1 | 13 | 29 | 31 | 377 | 403 | 899 | 11,687 | 48,187 | 626,431 | 1,397,423 | 1,493,797 | 18,166,499 | 19,419,361 | 43,320,113 | 563,161,469 |
| -1 | -13 | -29 | -31 | -377 | -403 | -899 | -11,687 | -48,187 | -626,431 | -1,397,423 | -1,493,797 | -18,166,499 | -19,419,361 | -43,320,113 | -563,161,469 |
