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 206,499,295, 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 | 206,499,295 | |
| -1 | -206,499,295 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 206,499,295.
Example:
1 x 206,499,295 = 206,499,295
and
-1 x -206,499,295 = 206,499,295
Notice both answers equal 206,499,295
With that explanation out of the way, let's continue. Next, we take the number 206,499,295 and divide it by 2:
206,499,295 ÷ 2 = 103,249,647.5
If the quotient is a whole number, then 2 and 103,249,647.5 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 | 206,499,295 | |
| -1 | -206,499,295 |
Now, we try dividing 206,499,295 by 3:
206,499,295 ÷ 3 = 68,833,098.3333
If the quotient is a whole number, then 3 and 68,833,098.3333 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 | 206,499,295 | |
| -1 | -206,499,295 |
Let's try dividing by 4:
206,499,295 ÷ 4 = 51,624,823.75
If the quotient is a whole number, then 4 and 51,624,823.75 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 | 206,499,295 | |
| -1 | 206,499,295 |
If you did it right, you will end up with this table:
| 1 | 5 | 151 | 479 | 571 | 755 | 2,395 | 2,855 | 72,329 | 86,221 | 273,509 | 361,645 | 431,105 | 1,367,545 | 41,299,859 | 206,499,295 |
| -1 | -5 | -151 | -479 | -571 | -755 | -2,395 | -2,855 | -72,329 | -86,221 | -273,509 | -361,645 | -431,105 | -1,367,545 | -41,299,859 | -206,499,295 |
