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 563,010,313, 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 | 563,010,313 | |
| -1 | -563,010,313 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 563,010,313.
Example:
1 x 563,010,313 = 563,010,313
and
-1 x -563,010,313 = 563,010,313
Notice both answers equal 563,010,313
With that explanation out of the way, let's continue. Next, we take the number 563,010,313 and divide it by 2:
563,010,313 ÷ 2 = 281,505,156.5
If the quotient is a whole number, then 2 and 281,505,156.5 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 | 563,010,313 | |
| -1 | -563,010,313 |
Now, we try dividing 563,010,313 by 3:
563,010,313 ÷ 3 = 187,670,104.3333
If the quotient is a whole number, then 3 and 187,670,104.3333 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 | 563,010,313 | |
| -1 | -563,010,313 |
Let's try dividing by 4:
563,010,313 ÷ 4 = 140,752,578.25
If the quotient is a whole number, then 4 and 140,752,578.25 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 | 563,010,313 | |
| -1 | 563,010,313 |
If you did it right, you will end up with this table:
| 1 | 31 | 67 | 163 | 1,663 | 2,077 | 5,053 | 10,921 | 51,553 | 111,421 | 271,069 | 338,551 | 3,454,051 | 8,403,139 | 18,161,623 | 563,010,313 |
| -1 | -31 | -67 | -163 | -1,663 | -2,077 | -5,053 | -10,921 | -51,553 | -111,421 | -271,069 | -338,551 | -3,454,051 | -8,403,139 | -18,161,623 | -563,010,313 |
