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 204,031,211, 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 | 204,031,211 | |
| -1 | -204,031,211 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 204,031,211.
Example:
1 x 204,031,211 = 204,031,211
and
-1 x -204,031,211 = 204,031,211
Notice both answers equal 204,031,211
With that explanation out of the way, let's continue. Next, we take the number 204,031,211 and divide it by 2:
204,031,211 ÷ 2 = 102,015,605.5
If the quotient is a whole number, then 2 and 102,015,605.5 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 | 204,031,211 | |
| -1 | -204,031,211 |
Now, we try dividing 204,031,211 by 3:
204,031,211 ÷ 3 = 68,010,403.6667
If the quotient is a whole number, then 3 and 68,010,403.6667 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 | 204,031,211 | |
| -1 | -204,031,211 |
Let's try dividing by 4:
204,031,211 ÷ 4 = 51,007,802.75
If the quotient is a whole number, then 4 and 51,007,802.75 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 | 204,031,211 | |
| -1 | 204,031,211 |
If you did it right, you will end up with this table:
| 1 | 29 | 41 | 101 | 1,189 | 1,699 | 2,929 | 4,141 | 49,271 | 69,659 | 120,089 | 171,599 | 2,020,111 | 4,976,371 | 7,035,559 | 204,031,211 |
| -1 | -29 | -41 | -101 | -1,189 | -1,699 | -2,929 | -4,141 | -49,271 | -69,659 | -120,089 | -171,599 | -2,020,111 | -4,976,371 | -7,035,559 | -204,031,211 |
