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 503,032,415, 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 | 503,032,415 | |
| -1 | -503,032,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 503,032,415.
Example:
1 x 503,032,415 = 503,032,415
and
-1 x -503,032,415 = 503,032,415
Notice both answers equal 503,032,415
With that explanation out of the way, let's continue. Next, we take the number 503,032,415 and divide it by 2:
503,032,415 ÷ 2 = 251,516,207.5
If the quotient is a whole number, then 2 and 251,516,207.5 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 | 503,032,415 | |
| -1 | -503,032,415 |
Now, we try dividing 503,032,415 by 3:
503,032,415 ÷ 3 = 167,677,471.6667
If the quotient is a whole number, then 3 and 167,677,471.6667 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 | 503,032,415 | |
| -1 | -503,032,415 |
Let's try dividing by 4:
503,032,415 ÷ 4 = 125,758,103.75
If the quotient is a whole number, then 4 and 125,758,103.75 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 | 503,032,415 | |
| -1 | 503,032,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 73 | 365 | 761 | 1,811 | 3,805 | 9,055 | 55,553 | 132,203 | 277,765 | 661,015 | 1,378,171 | 6,890,855 | 100,606,483 | 503,032,415 |
| -1 | -5 | -73 | -365 | -761 | -1,811 | -3,805 | -9,055 | -55,553 | -132,203 | -277,765 | -661,015 | -1,378,171 | -6,890,855 | -100,606,483 | -503,032,415 |
