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 581,850,205, 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 | 581,850,205 | |
| -1 | -581,850,205 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 581,850,205.
Example:
1 x 581,850,205 = 581,850,205
and
-1 x -581,850,205 = 581,850,205
Notice both answers equal 581,850,205
With that explanation out of the way, let's continue. Next, we take the number 581,850,205 and divide it by 2:
581,850,205 ÷ 2 = 290,925,102.5
If the quotient is a whole number, then 2 and 290,925,102.5 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 | 581,850,205 | |
| -1 | -581,850,205 |
Now, we try dividing 581,850,205 by 3:
581,850,205 ÷ 3 = 193,950,068.3333
If the quotient is a whole number, then 3 and 193,950,068.3333 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 | 581,850,205 | |
| -1 | -581,850,205 |
Let's try dividing by 4:
581,850,205 ÷ 4 = 145,462,551.25
If the quotient is a whole number, then 4 and 145,462,551.25 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 | 581,850,205 | |
| -1 | 581,850,205 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 23 | 95 | 115 | 437 | 2,185 | 266,293 | 1,331,465 | 5,059,567 | 6,124,739 | 25,297,835 | 30,623,695 | 116,370,041 | 581,850,205 |
| -1 | -5 | -19 | -23 | -95 | -115 | -437 | -2,185 | -266,293 | -1,331,465 | -5,059,567 | -6,124,739 | -25,297,835 | -30,623,695 | -116,370,041 | -581,850,205 |
