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 206,272,265, 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 | 206,272,265 | |
| -1 | -206,272,265 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 206,272,265.
Example:
1 x 206,272,265 = 206,272,265
and
-1 x -206,272,265 = 206,272,265
Notice both answers equal 206,272,265
With that explanation out of the way, let's continue. Next, we take the number 206,272,265 and divide it by 2:
206,272,265 ÷ 2 = 103,136,132.5
If the quotient is a whole number, then 2 and 103,136,132.5 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 | 206,272,265 | |
| -1 | -206,272,265 |
Now, we try dividing 206,272,265 by 3:
206,272,265 ÷ 3 = 68,757,421.6667
If the quotient is a whole number, then 3 and 68,757,421.6667 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 | 206,272,265 | |
| -1 | -206,272,265 |
Let's try dividing by 4:
206,272,265 ÷ 4 = 51,568,066.25
If the quotient is a whole number, then 4 and 51,568,066.25 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 | 206,272,265 | |
| -1 | 206,272,265 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 281 | 1,405 | 5,339 | 7,727 | 26,695 | 38,635 | 146,813 | 734,065 | 2,171,287 | 10,856,435 | 41,254,453 | 206,272,265 |
| -1 | -5 | -19 | -95 | -281 | -1,405 | -5,339 | -7,727 | -26,695 | -38,635 | -146,813 | -734,065 | -2,171,287 | -10,856,435 | -41,254,453 | -206,272,265 |
