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 203,022,449, 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 | 203,022,449 | |
| -1 | -203,022,449 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 203,022,449.
Example:
1 x 203,022,449 = 203,022,449
and
-1 x -203,022,449 = 203,022,449
Notice both answers equal 203,022,449
With that explanation out of the way, let's continue. Next, we take the number 203,022,449 and divide it by 2:
203,022,449 ÷ 2 = 101,511,224.5
If the quotient is a whole number, then 2 and 101,511,224.5 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 | 203,022,449 | |
| -1 | -203,022,449 |
Now, we try dividing 203,022,449 by 3:
203,022,449 ÷ 3 = 67,674,149.6667
If the quotient is a whole number, then 3 and 67,674,149.6667 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 | 203,022,449 | |
| -1 | -203,022,449 |
Let's try dividing by 4:
203,022,449 ÷ 4 = 50,755,612.25
If the quotient is a whole number, then 4 and 50,755,612.25 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 | 203,022,449 | |
| -1 | 203,022,449 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 23 | 119 | 161 | 391 | 2,737 | 74,177 | 519,239 | 1,261,009 | 1,706,071 | 8,827,063 | 11,942,497 | 29,003,207 | 203,022,449 |
| -1 | -7 | -17 | -23 | -119 | -161 | -391 | -2,737 | -74,177 | -519,239 | -1,261,009 | -1,706,071 | -8,827,063 | -11,942,497 | -29,003,207 | -203,022,449 |
