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 555,347,213, 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 | 555,347,213 | |
| -1 | -555,347,213 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 555,347,213.
Example:
1 x 555,347,213 = 555,347,213
and
-1 x -555,347,213 = 555,347,213
Notice both answers equal 555,347,213
With that explanation out of the way, let's continue. Next, we take the number 555,347,213 and divide it by 2:
555,347,213 ÷ 2 = 277,673,606.5
If the quotient is a whole number, then 2 and 277,673,606.5 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 | 555,347,213 | |
| -1 | -555,347,213 |
Now, we try dividing 555,347,213 by 3:
555,347,213 ÷ 3 = 185,115,737.6667
If the quotient is a whole number, then 3 and 185,115,737.6667 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 | 555,347,213 | |
| -1 | -555,347,213 |
Let's try dividing by 4:
555,347,213 ÷ 4 = 138,836,803.25
If the quotient is a whole number, then 4 and 138,836,803.25 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 | 555,347,213 | |
| -1 | 555,347,213 |
If you did it right, you will end up with this table:
| 1 | 23 | 97 | 229 | 1,087 | 2,231 | 5,267 | 22,213 | 25,001 | 105,439 | 248,923 | 510,899 | 2,425,097 | 5,725,229 | 24,145,531 | 555,347,213 |
| -1 | -23 | -97 | -229 | -1,087 | -2,231 | -5,267 | -22,213 | -25,001 | -105,439 | -248,923 | -510,899 | -2,425,097 | -5,725,229 | -24,145,531 | -555,347,213 |
