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 531,348,205, 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 | 531,348,205 | |
| -1 | -531,348,205 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 531,348,205.
Example:
1 x 531,348,205 = 531,348,205
and
-1 x -531,348,205 = 531,348,205
Notice both answers equal 531,348,205
With that explanation out of the way, let's continue. Next, we take the number 531,348,205 and divide it by 2:
531,348,205 ÷ 2 = 265,674,102.5
If the quotient is a whole number, then 2 and 265,674,102.5 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 | 531,348,205 | |
| -1 | -531,348,205 |
Now, we try dividing 531,348,205 by 3:
531,348,205 ÷ 3 = 177,116,068.3333
If the quotient is a whole number, then 3 and 177,116,068.3333 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 | 531,348,205 | |
| -1 | -531,348,205 |
Let's try dividing by 4:
531,348,205 ÷ 4 = 132,837,051.25
If the quotient is a whole number, then 4 and 132,837,051.25 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 | 531,348,205 | |
| -1 | 531,348,205 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 43 | 95 | 215 | 817 | 4,085 | 130,073 | 650,365 | 2,471,387 | 5,593,139 | 12,356,935 | 27,965,695 | 106,269,641 | 531,348,205 |
| -1 | -5 | -19 | -43 | -95 | -215 | -817 | -4,085 | -130,073 | -650,365 | -2,471,387 | -5,593,139 | -12,356,935 | -27,965,695 | -106,269,641 | -531,348,205 |
