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 556,338,685, 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 | 556,338,685 | |
| -1 | -556,338,685 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 556,338,685.
Example:
1 x 556,338,685 = 556,338,685
and
-1 x -556,338,685 = 556,338,685
Notice both answers equal 556,338,685
With that explanation out of the way, let's continue. Next, we take the number 556,338,685 and divide it by 2:
556,338,685 ÷ 2 = 278,169,342.5
If the quotient is a whole number, then 2 and 278,169,342.5 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 | 556,338,685 | |
| -1 | -556,338,685 |
Now, we try dividing 556,338,685 by 3:
556,338,685 ÷ 3 = 185,446,228.3333
If the quotient is a whole number, then 3 and 185,446,228.3333 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 | 556,338,685 | |
| -1 | -556,338,685 |
Let's try dividing by 4:
556,338,685 ÷ 4 = 139,084,671.25
If the quotient is a whole number, then 4 and 139,084,671.25 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 | 556,338,685 | |
| -1 | 556,338,685 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 17 | 35 | 85 | 119 | 595 | 935,023 | 4,675,115 | 6,545,161 | 15,895,391 | 32,725,805 | 79,476,955 | 111,267,737 | 556,338,685 |
| -1 | -5 | -7 | -17 | -35 | -85 | -119 | -595 | -935,023 | -4,675,115 | -6,545,161 | -15,895,391 | -32,725,805 | -79,476,955 | -111,267,737 | -556,338,685 |
