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 202,665,505, 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 | 202,665,505 | |
| -1 | -202,665,505 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 202,665,505.
Example:
1 x 202,665,505 = 202,665,505
and
-1 x -202,665,505 = 202,665,505
Notice both answers equal 202,665,505
With that explanation out of the way, let's continue. Next, we take the number 202,665,505 and divide it by 2:
202,665,505 ÷ 2 = 101,332,752.5
If the quotient is a whole number, then 2 and 101,332,752.5 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 | 202,665,505 | |
| -1 | -202,665,505 |
Now, we try dividing 202,665,505 by 3:
202,665,505 ÷ 3 = 67,555,168.3333
If the quotient is a whole number, then 3 and 67,555,168.3333 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 | 202,665,505 | |
| -1 | -202,665,505 |
Let's try dividing by 4:
202,665,505 ÷ 4 = 50,666,376.25
If the quotient is a whole number, then 4 and 50,666,376.25 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 | 202,665,505 | |
| -1 | 202,665,505 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 1,181 | 4,903 | 5,905 | 8,267 | 24,515 | 34,321 | 41,335 | 171,605 | 5,790,443 | 28,952,215 | 40,533,101 | 202,665,505 |
| -1 | -5 | -7 | -35 | -1,181 | -4,903 | -5,905 | -8,267 | -24,515 | -34,321 | -41,335 | -171,605 | -5,790,443 | -28,952,215 | -40,533,101 | -202,665,505 |
