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 530,887,877, 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 | 530,887,877 | |
| -1 | -530,887,877 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 530,887,877.
Example:
1 x 530,887,877 = 530,887,877
and
-1 x -530,887,877 = 530,887,877
Notice both answers equal 530,887,877
With that explanation out of the way, let's continue. Next, we take the number 530,887,877 and divide it by 2:
530,887,877 ÷ 2 = 265,443,938.5
If the quotient is a whole number, then 2 and 265,443,938.5 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 | 530,887,877 | |
| -1 | -530,887,877 |
Now, we try dividing 530,887,877 by 3:
530,887,877 ÷ 3 = 176,962,625.6667
If the quotient is a whole number, then 3 and 176,962,625.6667 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 | 530,887,877 | |
| -1 | -530,887,877 |
Let's try dividing by 4:
530,887,877 ÷ 4 = 132,721,969.25
If the quotient is a whole number, then 4 and 132,721,969.25 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 | 530,887,877 | |
| -1 | 530,887,877 |
If you did it right, you will end up with this table:
| 1 | 13 | 37 | 433 | 481 | 2,549 | 5,629 | 16,021 | 33,137 | 94,313 | 208,273 | 1,103,717 | 1,226,069 | 14,348,321 | 40,837,529 | 530,887,877 |
| -1 | -13 | -37 | -433 | -481 | -2,549 | -5,629 | -16,021 | -33,137 | -94,313 | -208,273 | -1,103,717 | -1,226,069 | -14,348,321 | -40,837,529 | -530,887,877 |
