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 555,753,565, 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 | 555,753,565 | |
| -1 | -555,753,565 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 555,753,565.
Example:
1 x 555,753,565 = 555,753,565
and
-1 x -555,753,565 = 555,753,565
Notice both answers equal 555,753,565
With that explanation out of the way, let's continue. Next, we take the number 555,753,565 and divide it by 2:
555,753,565 ÷ 2 = 277,876,782.5
If the quotient is a whole number, then 2 and 277,876,782.5 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 | 555,753,565 | |
| -1 | -555,753,565 |
Now, we try dividing 555,753,565 by 3:
555,753,565 ÷ 3 = 185,251,188.3333
If the quotient is a whole number, then 3 and 185,251,188.3333 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 | 555,753,565 | |
| -1 | -555,753,565 |
Let's try dividing by 4:
555,753,565 ÷ 4 = 138,938,391.25
If the quotient is a whole number, then 4 and 138,938,391.25 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 | 555,753,565 | |
| -1 | 555,753,565 |
If you did it right, you will end up with this table:
| 1 | 5 | 41 | 71 | 205 | 355 | 2,911 | 14,555 | 38,183 | 190,915 | 1,565,503 | 2,710,993 | 7,827,515 | 13,554,965 | 111,150,713 | 555,753,565 |
| -1 | -5 | -41 | -71 | -205 | -355 | -2,911 | -14,555 | -38,183 | -190,915 | -1,565,503 | -2,710,993 | -7,827,515 | -13,554,965 | -111,150,713 | -555,753,565 |
