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 203,666,225, 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 | 203,666,225 | |
| -1 | -203,666,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 203,666,225.
Example:
1 x 203,666,225 = 203,666,225
and
-1 x -203,666,225 = 203,666,225
Notice both answers equal 203,666,225
With that explanation out of the way, let's continue. Next, we take the number 203,666,225 and divide it by 2:
203,666,225 ÷ 2 = 101,833,112.5
If the quotient is a whole number, then 2 and 101,833,112.5 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 | 203,666,225 | |
| -1 | -203,666,225 |
Now, we try dividing 203,666,225 by 3:
203,666,225 ÷ 3 = 67,888,741.6667
If the quotient is a whole number, then 3 and 67,888,741.6667 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 | 203,666,225 | |
| -1 | -203,666,225 |
Let's try dividing by 4:
203,666,225 ÷ 4 = 50,916,556.25
If the quotient is a whole number, then 4 and 50,916,556.25 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 | 203,666,225 | |
| -1 | 203,666,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 19 | 25 | 35 | 95 | 133 | 175 | 475 | 665 | 3,325 | 61,253 | 306,265 | 428,771 | 1,163,807 | 1,531,325 | 2,143,855 | 5,819,035 | 8,146,649 | 10,719,275 | 29,095,175 | 40,733,245 | 203,666,225 |
| -1 | -5 | -7 | -19 | -25 | -35 | -95 | -133 | -175 | -475 | -665 | -3,325 | -61,253 | -306,265 | -428,771 | -1,163,807 | -1,531,325 | -2,143,855 | -5,819,035 | -8,146,649 | -10,719,275 | -29,095,175 | -40,733,245 | -203,666,225 |
