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 203,010,325, 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 | 203,010,325 | |
| -1 | -203,010,325 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 203,010,325.
Example:
1 x 203,010,325 = 203,010,325
and
-1 x -203,010,325 = 203,010,325
Notice both answers equal 203,010,325
With that explanation out of the way, let's continue. Next, we take the number 203,010,325 and divide it by 2:
203,010,325 ÷ 2 = 101,505,162.5
If the quotient is a whole number, then 2 and 101,505,162.5 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 | 203,010,325 | |
| -1 | -203,010,325 |
Now, we try dividing 203,010,325 by 3:
203,010,325 ÷ 3 = 67,670,108.3333
If the quotient is a whole number, then 3 and 67,670,108.3333 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 | 203,010,325 | |
| -1 | -203,010,325 |
Let's try dividing by 4:
203,010,325 ÷ 4 = 50,752,581.25
If the quotient is a whole number, then 4 and 50,752,581.25 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 | 203,010,325 | |
| -1 | 203,010,325 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 175 | 1,033 | 1,123 | 5,165 | 5,615 | 7,231 | 7,861 | 25,825 | 28,075 | 36,155 | 39,305 | 180,775 | 196,525 | 1,160,059 | 5,800,295 | 8,120,413 | 29,001,475 | 40,602,065 | 203,010,325 |
| -1 | -5 | -7 | -25 | -35 | -175 | -1,033 | -1,123 | -5,165 | -5,615 | -7,231 | -7,861 | -25,825 | -28,075 | -36,155 | -39,305 | -180,775 | -196,525 | -1,160,059 | -5,800,295 | -8,120,413 | -29,001,475 | -40,602,065 | -203,010,325 |
