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 563,131,049, 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 | 563,131,049 | |
| -1 | -563,131,049 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 563,131,049.
Example:
1 x 563,131,049 = 563,131,049
and
-1 x -563,131,049 = 563,131,049
Notice both answers equal 563,131,049
With that explanation out of the way, let's continue. Next, we take the number 563,131,049 and divide it by 2:
563,131,049 ÷ 2 = 281,565,524.5
If the quotient is a whole number, then 2 and 281,565,524.5 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 | 563,131,049 | |
| -1 | -563,131,049 |
Now, we try dividing 563,131,049 by 3:
563,131,049 ÷ 3 = 187,710,349.6667
If the quotient is a whole number, then 3 and 187,710,349.6667 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 | 563,131,049 | |
| -1 | -563,131,049 |
Let's try dividing by 4:
563,131,049 ÷ 4 = 140,782,762.25
If the quotient is a whole number, then 4 and 140,782,762.25 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 | 563,131,049 | |
| -1 | 563,131,049 |
If you did it right, you will end up with this table:
| 1 | 13 | 107 | 571 | 709 | 1,391 | 7,423 | 9,217 | 61,097 | 75,863 | 404,839 | 794,261 | 986,219 | 5,262,907 | 43,317,773 | 563,131,049 |
| -1 | -13 | -107 | -571 | -709 | -1,391 | -7,423 | -9,217 | -61,097 | -75,863 | -404,839 | -794,261 | -986,219 | -5,262,907 | -43,317,773 | -563,131,049 |
