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 531,158,705, 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 | 531,158,705 | |
| -1 | -531,158,705 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 531,158,705.
Example:
1 x 531,158,705 = 531,158,705
and
-1 x -531,158,705 = 531,158,705
Notice both answers equal 531,158,705
With that explanation out of the way, let's continue. Next, we take the number 531,158,705 and divide it by 2:
531,158,705 ÷ 2 = 265,579,352.5
If the quotient is a whole number, then 2 and 265,579,352.5 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 | 531,158,705 | |
| -1 | -531,158,705 |
Now, we try dividing 531,158,705 by 3:
531,158,705 ÷ 3 = 177,052,901.6667
If the quotient is a whole number, then 3 and 177,052,901.6667 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 | 531,158,705 | |
| -1 | -531,158,705 |
Let's try dividing by 4:
531,158,705 ÷ 4 = 132,789,676.25
If the quotient is a whole number, then 4 and 132,789,676.25 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 | 531,158,705 | |
| -1 | 531,158,705 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 35 | 55 | 77 | 385 | 1,379,633 | 6,898,165 | 9,657,431 | 15,175,963 | 48,287,155 | 75,879,815 | 106,231,741 | 531,158,705 |
| -1 | -5 | -7 | -11 | -35 | -55 | -77 | -385 | -1,379,633 | -6,898,165 | -9,657,431 | -15,175,963 | -48,287,155 | -75,879,815 | -106,231,741 | -531,158,705 |
