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 203,305,417, 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 | 203,305,417 | |
| -1 | -203,305,417 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 203,305,417.
Example:
1 x 203,305,417 = 203,305,417
and
-1 x -203,305,417 = 203,305,417
Notice both answers equal 203,305,417
With that explanation out of the way, let's continue. Next, we take the number 203,305,417 and divide it by 2:
203,305,417 ÷ 2 = 101,652,708.5
If the quotient is a whole number, then 2 and 101,652,708.5 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 | 203,305,417 | |
| -1 | -203,305,417 |
Now, we try dividing 203,305,417 by 3:
203,305,417 ÷ 3 = 67,768,472.3333
If the quotient is a whole number, then 3 and 67,768,472.3333 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 | 203,305,417 | |
| -1 | -203,305,417 |
Let's try dividing by 4:
203,305,417 ÷ 4 = 50,826,354.25
If the quotient is a whole number, then 4 and 50,826,354.25 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 | 203,305,417 | |
| -1 | 203,305,417 |
If you did it right, you will end up with this table:
| 1 | 7 | 37 | 103 | 259 | 721 | 3,811 | 7,621 | 26,677 | 53,347 | 281,977 | 784,963 | 1,973,839 | 5,494,741 | 29,043,631 | 203,305,417 |
| -1 | -7 | -37 | -103 | -259 | -721 | -3,811 | -7,621 | -26,677 | -53,347 | -281,977 | -784,963 | -1,973,839 | -5,494,741 | -29,043,631 | -203,305,417 |
