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 203,103,325, 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 | 203,103,325 | |
| -1 | -203,103,325 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 203,103,325.
Example:
1 x 203,103,325 = 203,103,325
and
-1 x -203,103,325 = 203,103,325
Notice both answers equal 203,103,325
With that explanation out of the way, let's continue. Next, we take the number 203,103,325 and divide it by 2:
203,103,325 ÷ 2 = 101,551,662.5
If the quotient is a whole number, then 2 and 101,551,662.5 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 | 203,103,325 | |
| -1 | -203,103,325 |
Now, we try dividing 203,103,325 by 3:
203,103,325 ÷ 3 = 67,701,108.3333
If the quotient is a whole number, then 3 and 67,701,108.3333 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 | 203,103,325 | |
| -1 | -203,103,325 |
Let's try dividing by 4:
203,103,325 ÷ 4 = 50,775,831.25
If the quotient is a whole number, then 4 and 50,775,831.25 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 | 203,103,325 | |
| -1 | 203,103,325 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 139 | 211 | 277 | 695 | 1,055 | 1,385 | 3,475 | 5,275 | 6,925 | 29,329 | 38,503 | 58,447 | 146,645 | 192,515 | 292,235 | 733,225 | 962,575 | 1,461,175 | 8,124,133 | 40,620,665 | 203,103,325 |
| -1 | -5 | -25 | -139 | -211 | -277 | -695 | -1,055 | -1,385 | -3,475 | -5,275 | -6,925 | -29,329 | -38,503 | -58,447 | -146,645 | -192,515 | -292,235 | -733,225 | -962,575 | -1,461,175 | -8,124,133 | -40,620,665 | -203,103,325 |
