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 203,245,505, 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 | 203,245,505 | |
| -1 | -203,245,505 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 203,245,505.
Example:
1 x 203,245,505 = 203,245,505
and
-1 x -203,245,505 = 203,245,505
Notice both answers equal 203,245,505
With that explanation out of the way, let's continue. Next, we take the number 203,245,505 and divide it by 2:
203,245,505 ÷ 2 = 101,622,752.5
If the quotient is a whole number, then 2 and 101,622,752.5 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 | 203,245,505 | |
| -1 | -203,245,505 |
Now, we try dividing 203,245,505 by 3:
203,245,505 ÷ 3 = 67,748,501.6667
If the quotient is a whole number, then 3 and 67,748,501.6667 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 | 203,245,505 | |
| -1 | -203,245,505 |
Let's try dividing by 4:
203,245,505 ÷ 4 = 50,811,376.25
If the quotient is a whole number, then 4 and 50,811,376.25 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 | 203,245,505 | |
| -1 | 203,245,505 |
If you did it right, you will end up with this table:
| 1 | 5 | 67 | 73 | 335 | 365 | 4,891 | 8,311 | 24,455 | 41,555 | 556,837 | 606,703 | 2,784,185 | 3,033,515 | 40,649,101 | 203,245,505 |
| -1 | -5 | -67 | -73 | -335 | -365 | -4,891 | -8,311 | -24,455 | -41,555 | -556,837 | -606,703 | -2,784,185 | -3,033,515 | -40,649,101 | -203,245,505 |
