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 555,775, 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 | 555,775 | |
| -1 | -555,775 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 555,775.
Example:
1 x 555,775 = 555,775
and
-1 x -555,775 = 555,775
Notice both answers equal 555,775
With that explanation out of the way, let's continue. Next, we take the number 555,775 and divide it by 2:
555,775 ÷ 2 = 277,887.5
If the quotient is a whole number, then 2 and 277,887.5 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 | 555,775 | |
| -1 | -555,775 |
Now, we try dividing 555,775 by 3:
555,775 ÷ 3 = 185,258.3333
If the quotient is a whole number, then 3 and 185,258.3333 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 | 555,775 | |
| -1 | -555,775 |
Let's try dividing by 4:
555,775 ÷ 4 = 138,943.75
If the quotient is a whole number, then 4 and 138,943.75 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 | 555,775 | |
| -1 | 555,775 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 43 | 47 | 55 | 215 | 235 | 275 | 473 | 517 | 1,075 | 1,175 | 2,021 | 2,365 | 2,585 | 10,105 | 11,825 | 12,925 | 22,231 | 50,525 | 111,155 | 555,775 |
| -1 | -5 | -11 | -25 | -43 | -47 | -55 | -215 | -235 | -275 | -473 | -517 | -1,075 | -1,175 | -2,021 | -2,365 | -2,585 | -10,105 | -11,825 | -12,925 | -22,231 | -50,525 | -111,155 | -555,775 |
