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 555,603,415, 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 | 555,603,415 | |
| -1 | -555,603,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 555,603,415.
Example:
1 x 555,603,415 = 555,603,415
and
-1 x -555,603,415 = 555,603,415
Notice both answers equal 555,603,415
With that explanation out of the way, let's continue. Next, we take the number 555,603,415 and divide it by 2:
555,603,415 ÷ 2 = 277,801,707.5
If the quotient is a whole number, then 2 and 277,801,707.5 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 | 555,603,415 | |
| -1 | -555,603,415 |
Now, we try dividing 555,603,415 by 3:
555,603,415 ÷ 3 = 185,201,138.3333
If the quotient is a whole number, then 3 and 185,201,138.3333 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 | 555,603,415 | |
| -1 | -555,603,415 |
Let's try dividing by 4:
555,603,415 ÷ 4 = 138,900,853.75
If the quotient is a whole number, then 4 and 138,900,853.75 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 | 555,603,415 | |
| -1 | 555,603,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 89 | 95 | 445 | 1,691 | 8,455 | 65,713 | 328,565 | 1,248,547 | 5,848,457 | 6,242,735 | 29,242,285 | 111,120,683 | 555,603,415 |
| -1 | -5 | -19 | -89 | -95 | -445 | -1,691 | -8,455 | -65,713 | -328,565 | -1,248,547 | -5,848,457 | -6,242,735 | -29,242,285 | -111,120,683 | -555,603,415 |
