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 505,035,533, 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 | 505,035,533 | |
| -1 | -505,035,533 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 505,035,533.
Example:
1 x 505,035,533 = 505,035,533
and
-1 x -505,035,533 = 505,035,533
Notice both answers equal 505,035,533
With that explanation out of the way, let's continue. Next, we take the number 505,035,533 and divide it by 2:
505,035,533 ÷ 2 = 252,517,766.5
If the quotient is a whole number, then 2 and 252,517,766.5 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 | 505,035,533 | |
| -1 | -505,035,533 |
Now, we try dividing 505,035,533 by 3:
505,035,533 ÷ 3 = 168,345,177.6667
If the quotient is a whole number, then 3 and 168,345,177.6667 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 | 505,035,533 | |
| -1 | -505,035,533 |
Let's try dividing by 4:
505,035,533 ÷ 4 = 126,258,883.25
If the quotient is a whole number, then 4 and 126,258,883.25 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 | 505,035,533 | |
| -1 | 505,035,533 |
If you did it right, you will end up with this table:
| 1 | 37 | 113 | 199 | 607 | 4,181 | 7,363 | 22,459 | 22,487 | 68,591 | 120,793 | 832,019 | 2,537,867 | 4,469,341 | 13,649,609 | 505,035,533 |
| -1 | -37 | -113 | -199 | -607 | -4,181 | -7,363 | -22,459 | -22,487 | -68,591 | -120,793 | -832,019 | -2,537,867 | -4,469,341 | -13,649,609 | -505,035,533 |
