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 580,185,863, 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 | 580,185,863 | |
| -1 | -580,185,863 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 580,185,863.
Example:
1 x 580,185,863 = 580,185,863
and
-1 x -580,185,863 = 580,185,863
Notice both answers equal 580,185,863
With that explanation out of the way, let's continue. Next, we take the number 580,185,863 and divide it by 2:
580,185,863 ÷ 2 = 290,092,931.5
If the quotient is a whole number, then 2 and 290,092,931.5 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 | 580,185,863 | |
| -1 | -580,185,863 |
Now, we try dividing 580,185,863 by 3:
580,185,863 ÷ 3 = 193,395,287.6667
If the quotient is a whole number, then 3 and 193,395,287.6667 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 | 580,185,863 | |
| -1 | -580,185,863 |
Let's try dividing by 4:
580,185,863 ÷ 4 = 145,046,465.75
If the quotient is a whole number, then 4 and 145,046,465.75 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 | 580,185,863 | |
| -1 | 580,185,863 |
If you did it right, you will end up with this table:
| 1 | 31 | 37 | 593 | 853 | 1,147 | 18,383 | 21,941 | 26,443 | 31,561 | 505,829 | 680,171 | 978,391 | 15,680,699 | 18,715,673 | 580,185,863 |
| -1 | -31 | -37 | -593 | -853 | -1,147 | -18,383 | -21,941 | -26,443 | -31,561 | -505,829 | -680,171 | -978,391 | -15,680,699 | -18,715,673 | -580,185,863 |
