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 553,246,127, 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 | 553,246,127 | |
| -1 | -553,246,127 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 553,246,127.
Example:
1 x 553,246,127 = 553,246,127
and
-1 x -553,246,127 = 553,246,127
Notice both answers equal 553,246,127
With that explanation out of the way, let's continue. Next, we take the number 553,246,127 and divide it by 2:
553,246,127 ÷ 2 = 276,623,063.5
If the quotient is a whole number, then 2 and 276,623,063.5 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 | 553,246,127 | |
| -1 | -553,246,127 |
Now, we try dividing 553,246,127 by 3:
553,246,127 ÷ 3 = 184,415,375.6667
If the quotient is a whole number, then 3 and 184,415,375.6667 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 | 553,246,127 | |
| -1 | -553,246,127 |
Let's try dividing by 4:
553,246,127 ÷ 4 = 138,311,531.75
If the quotient is a whole number, then 4 and 138,311,531.75 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 | 553,246,127 | |
| -1 | 553,246,127 |
If you did it right, you will end up with this table:
| 1 | 7 | 43 | 59 | 301 | 413 | 2,537 | 17,759 | 31,153 | 218,071 | 1,339,579 | 1,838,027 | 9,377,053 | 12,866,189 | 79,035,161 | 553,246,127 |
| -1 | -7 | -43 | -59 | -301 | -413 | -2,537 | -17,759 | -31,153 | -218,071 | -1,339,579 | -1,838,027 | -9,377,053 | -12,866,189 | -79,035,161 | -553,246,127 |
