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 202,666,265, 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 | 202,666,265 | |
| -1 | -202,666,265 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 202,666,265.
Example:
1 x 202,666,265 = 202,666,265
and
-1 x -202,666,265 = 202,666,265
Notice both answers equal 202,666,265
With that explanation out of the way, let's continue. Next, we take the number 202,666,265 and divide it by 2:
202,666,265 ÷ 2 = 101,333,132.5
If the quotient is a whole number, then 2 and 101,333,132.5 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 | 202,666,265 | |
| -1 | -202,666,265 |
Now, we try dividing 202,666,265 by 3:
202,666,265 ÷ 3 = 67,555,421.6667
If the quotient is a whole number, then 3 and 67,555,421.6667 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 | 202,666,265 | |
| -1 | -202,666,265 |
Let's try dividing by 4:
202,666,265 ÷ 4 = 50,666,566.25
If the quotient is a whole number, then 4 and 50,666,566.25 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 | 202,666,265 | |
| -1 | 202,666,265 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 1,063 | 2,243 | 5,315 | 11,215 | 18,071 | 38,131 | 90,355 | 190,655 | 2,384,309 | 11,921,545 | 40,533,253 | 202,666,265 |
| -1 | -5 | -17 | -85 | -1,063 | -2,243 | -5,315 | -11,215 | -18,071 | -38,131 | -90,355 | -190,655 | -2,384,309 | -11,921,545 | -40,533,253 | -202,666,265 |
