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 563,661,625, 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 | 563,661,625 | |
| -1 | -563,661,625 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 563,661,625.
Example:
1 x 563,661,625 = 563,661,625
and
-1 x -563,661,625 = 563,661,625
Notice both answers equal 563,661,625
With that explanation out of the way, let's continue. Next, we take the number 563,661,625 and divide it by 2:
563,661,625 ÷ 2 = 281,830,812.5
If the quotient is a whole number, then 2 and 281,830,812.5 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 | 563,661,625 | |
| -1 | -563,661,625 |
Now, we try dividing 563,661,625 by 3:
563,661,625 ÷ 3 = 187,887,208.3333
If the quotient is a whole number, then 3 and 187,887,208.3333 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 | 563,661,625 | |
| -1 | -563,661,625 |
Let's try dividing by 4:
563,661,625 ÷ 4 = 140,915,406.25
If the quotient is a whole number, then 4 and 140,915,406.25 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 | 563,661,625 | |
| -1 | 563,661,625 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 53 | 125 | 265 | 1,325 | 6,625 | 85,081 | 425,405 | 2,127,025 | 4,509,293 | 10,635,125 | 22,546,465 | 112,732,325 | 563,661,625 |
| -1 | -5 | -25 | -53 | -125 | -265 | -1,325 | -6,625 | -85,081 | -425,405 | -2,127,025 | -4,509,293 | -10,635,125 | -22,546,465 | -112,732,325 | -563,661,625 |
