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 504,637,105, 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 | 504,637,105 | |
| -1 | -504,637,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 504,637,105.
Example:
1 x 504,637,105 = 504,637,105
and
-1 x -504,637,105 = 504,637,105
Notice both answers equal 504,637,105
With that explanation out of the way, let's continue. Next, we take the number 504,637,105 and divide it by 2:
504,637,105 ÷ 2 = 252,318,552.5
If the quotient is a whole number, then 2 and 252,318,552.5 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 | 504,637,105 | |
| -1 | -504,637,105 |
Now, we try dividing 504,637,105 by 3:
504,637,105 ÷ 3 = 168,212,368.3333
If the quotient is a whole number, then 3 and 168,212,368.3333 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 | 504,637,105 | |
| -1 | -504,637,105 |
Let's try dividing by 4:
504,637,105 ÷ 4 = 126,159,276.25
If the quotient is a whole number, then 4 and 126,159,276.25 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 | 504,637,105 | |
| -1 | 504,637,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 1,039 | 5,195 | 7,273 | 13,877 | 36,365 | 69,385 | 97,139 | 485,695 | 14,418,203 | 72,091,015 | 100,927,421 | 504,637,105 |
| -1 | -5 | -7 | -35 | -1,039 | -5,195 | -7,273 | -13,877 | -36,365 | -69,385 | -97,139 | -485,695 | -14,418,203 | -72,091,015 | -100,927,421 | -504,637,105 |
