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 203,203,297, 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 | 203,203,297 | |
| -1 | -203,203,297 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 203,203,297.
Example:
1 x 203,203,297 = 203,203,297
and
-1 x -203,203,297 = 203,203,297
Notice both answers equal 203,203,297
With that explanation out of the way, let's continue. Next, we take the number 203,203,297 and divide it by 2:
203,203,297 ÷ 2 = 101,601,648.5
If the quotient is a whole number, then 2 and 101,601,648.5 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 | 203,203,297 | |
| -1 | -203,203,297 |
Now, we try dividing 203,203,297 by 3:
203,203,297 ÷ 3 = 67,734,432.3333
If the quotient is a whole number, then 3 and 67,734,432.3333 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 | 203,203,297 | |
| -1 | -203,203,297 |
Let's try dividing by 4:
203,203,297 ÷ 4 = 50,800,824.25
If the quotient is a whole number, then 4 and 50,800,824.25 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 | 203,203,297 | |
| -1 | 203,203,297 |
If you did it right, you will end up with this table:
| 1 | 11 | 37 | 239 | 407 | 2,089 | 2,629 | 8,843 | 22,979 | 77,293 | 97,273 | 499,271 | 850,223 | 5,491,981 | 18,473,027 | 203,203,297 |
| -1 | -11 | -37 | -239 | -407 | -2,089 | -2,629 | -8,843 | -22,979 | -77,293 | -97,273 | -499,271 | -850,223 | -5,491,981 | -18,473,027 | -203,203,297 |
