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 203,010,413, 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 | 203,010,413 | |
| -1 | -203,010,413 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 203,010,413.
Example:
1 x 203,010,413 = 203,010,413
and
-1 x -203,010,413 = 203,010,413
Notice both answers equal 203,010,413
With that explanation out of the way, let's continue. Next, we take the number 203,010,413 and divide it by 2:
203,010,413 ÷ 2 = 101,505,206.5
If the quotient is a whole number, then 2 and 101,505,206.5 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 | 203,010,413 | |
| -1 | -203,010,413 |
Now, we try dividing 203,010,413 by 3:
203,010,413 ÷ 3 = 67,670,137.6667
If the quotient is a whole number, then 3 and 67,670,137.6667 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 | 203,010,413 | |
| -1 | -203,010,413 |
Let's try dividing by 4:
203,010,413 ÷ 4 = 50,752,603.25
If the quotient is a whole number, then 4 and 50,752,603.25 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 | 203,010,413 | |
| -1 | 203,010,413 |
If you did it right, you will end up with this table:
| 1 | 17 | 31 | 227 | 527 | 1,697 | 3,859 | 7,037 | 28,849 | 52,607 | 119,629 | 385,219 | 894,319 | 6,548,723 | 11,941,789 | 203,010,413 |
| -1 | -17 | -31 | -227 | -527 | -1,697 | -3,859 | -7,037 | -28,849 | -52,607 | -119,629 | -385,219 | -894,319 | -6,548,723 | -11,941,789 | -203,010,413 |
