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 563,824,105, 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 | 563,824,105 | |
| -1 | -563,824,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 563,824,105.
Example:
1 x 563,824,105 = 563,824,105
and
-1 x -563,824,105 = 563,824,105
Notice both answers equal 563,824,105
With that explanation out of the way, let's continue. Next, we take the number 563,824,105 and divide it by 2:
563,824,105 ÷ 2 = 281,912,052.5
If the quotient is a whole number, then 2 and 281,912,052.5 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 | 563,824,105 | |
| -1 | -563,824,105 |
Now, we try dividing 563,824,105 by 3:
563,824,105 ÷ 3 = 187,941,368.3333
If the quotient is a whole number, then 3 and 187,941,368.3333 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 | 563,824,105 | |
| -1 | -563,824,105 |
Let's try dividing by 4:
563,824,105 ÷ 4 = 140,956,026.25
If the quotient is a whole number, then 4 and 140,956,026.25 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 | 563,824,105 | |
| -1 | 563,824,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 1,481 | 5,857 | 7,405 | 19,253 | 29,285 | 76,141 | 96,265 | 380,705 | 8,674,217 | 43,371,085 | 112,764,821 | 563,824,105 |
| -1 | -5 | -13 | -65 | -1,481 | -5,857 | -7,405 | -19,253 | -29,285 | -76,141 | -96,265 | -380,705 | -8,674,217 | -43,371,085 | -112,764,821 | -563,824,105 |
