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 203,633,345, 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 | 203,633,345 | |
| -1 | -203,633,345 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 203,633,345.
Example:
1 x 203,633,345 = 203,633,345
and
-1 x -203,633,345 = 203,633,345
Notice both answers equal 203,633,345
With that explanation out of the way, let's continue. Next, we take the number 203,633,345 and divide it by 2:
203,633,345 ÷ 2 = 101,816,672.5
If the quotient is a whole number, then 2 and 101,816,672.5 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 | 203,633,345 | |
| -1 | -203,633,345 |
Now, we try dividing 203,633,345 by 3:
203,633,345 ÷ 3 = 67,877,781.6667
If the quotient is a whole number, then 3 and 67,877,781.6667 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 | 203,633,345 | |
| -1 | -203,633,345 |
Let's try dividing by 4:
203,633,345 ÷ 4 = 50,908,336.25
If the quotient is a whole number, then 4 and 50,908,336.25 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 | 203,633,345 | |
| -1 | 203,633,345 |
If you did it right, you will end up with this table:
| 1 | 5 | 113 | 353 | 565 | 1,021 | 1,765 | 5,105 | 39,889 | 115,373 | 199,445 | 360,413 | 576,865 | 1,802,065 | 40,726,669 | 203,633,345 |
| -1 | -5 | -113 | -353 | -565 | -1,021 | -1,765 | -5,105 | -39,889 | -115,373 | -199,445 | -360,413 | -576,865 | -1,802,065 | -40,726,669 | -203,633,345 |
