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 553,553, 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 | 553,553 | |
| -1 | -553,553 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 553,553.
Example:
1 x 553,553 = 553,553
and
-1 x -553,553 = 553,553
Notice both answers equal 553,553
With that explanation out of the way, let's continue. Next, we take the number 553,553 and divide it by 2:
553,553 ÷ 2 = 276,776.5
If the quotient is a whole number, then 2 and 276,776.5 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 | 553,553 | |
| -1 | -553,553 |
Now, we try dividing 553,553 by 3:
553,553 ÷ 3 = 184,517.6667
If the quotient is a whole number, then 3 and 184,517.6667 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 | 553,553 | |
| -1 | -553,553 |
Let's try dividing by 4:
553,553 ÷ 4 = 138,388.25
If the quotient is a whole number, then 4 and 138,388.25 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 | 553,553 | |
| -1 | 553,553 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 13 | 49 | 77 | 79 | 91 | 143 | 539 | 553 | 637 | 869 | 1,001 | 1,027 | 3,871 | 6,083 | 7,007 | 7,189 | 11,297 | 42,581 | 50,323 | 79,079 | 553,553 |
| -1 | -7 | -11 | -13 | -49 | -77 | -79 | -91 | -143 | -539 | -553 | -637 | -869 | -1,001 | -1,027 | -3,871 | -6,083 | -7,007 | -7,189 | -11,297 | -42,581 | -50,323 | -79,079 | -553,553 |
