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 203,230,645, 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 | 203,230,645 | |
| -1 | -203,230,645 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 203,230,645.
Example:
1 x 203,230,645 = 203,230,645
and
-1 x -203,230,645 = 203,230,645
Notice both answers equal 203,230,645
With that explanation out of the way, let's continue. Next, we take the number 203,230,645 and divide it by 2:
203,230,645 ÷ 2 = 101,615,322.5
If the quotient is a whole number, then 2 and 101,615,322.5 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 | 203,230,645 | |
| -1 | -203,230,645 |
Now, we try dividing 203,230,645 by 3:
203,230,645 ÷ 3 = 67,743,548.3333
If the quotient is a whole number, then 3 and 67,743,548.3333 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 | 203,230,645 | |
| -1 | -203,230,645 |
Let's try dividing by 4:
203,230,645 ÷ 4 = 50,807,661.25
If the quotient is a whole number, then 4 and 50,807,661.25 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 | 203,230,645 | |
| -1 | 203,230,645 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 41 | 115 | 205 | 943 | 4,715 | 43,103 | 215,515 | 991,369 | 1,767,223 | 4,956,845 | 8,836,115 | 40,646,129 | 203,230,645 |
| -1 | -5 | -23 | -41 | -115 | -205 | -943 | -4,715 | -43,103 | -215,515 | -991,369 | -1,767,223 | -4,956,845 | -8,836,115 | -40,646,129 | -203,230,645 |
