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 204,353,015, 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 | 204,353,015 | |
| -1 | -204,353,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 204,353,015.
Example:
1 x 204,353,015 = 204,353,015
and
-1 x -204,353,015 = 204,353,015
Notice both answers equal 204,353,015
With that explanation out of the way, let's continue. Next, we take the number 204,353,015 and divide it by 2:
204,353,015 ÷ 2 = 102,176,507.5
If the quotient is a whole number, then 2 and 102,176,507.5 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 | 204,353,015 | |
| -1 | -204,353,015 |
Now, we try dividing 204,353,015 by 3:
204,353,015 ÷ 3 = 68,117,671.6667
If the quotient is a whole number, then 3 and 68,117,671.6667 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 | 204,353,015 | |
| -1 | -204,353,015 |
Let's try dividing by 4:
204,353,015 ÷ 4 = 51,088,253.75
If the quotient is a whole number, then 4 and 51,088,253.75 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 | 204,353,015 | |
| -1 | 204,353,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 67 | 307 | 335 | 1,535 | 1,987 | 9,935 | 20,569 | 102,845 | 133,129 | 610,009 | 665,645 | 3,050,045 | 40,870,603 | 204,353,015 |
| -1 | -5 | -67 | -307 | -335 | -1,535 | -1,987 | -9,935 | -20,569 | -102,845 | -133,129 | -610,009 | -665,645 | -3,050,045 | -40,870,603 | -204,353,015 |
