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 204,641,045, 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 | 204,641,045 | |
| -1 | -204,641,045 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 204,641,045.
Example:
1 x 204,641,045 = 204,641,045
and
-1 x -204,641,045 = 204,641,045
Notice both answers equal 204,641,045
With that explanation out of the way, let's continue. Next, we take the number 204,641,045 and divide it by 2:
204,641,045 ÷ 2 = 102,320,522.5
If the quotient is a whole number, then 2 and 102,320,522.5 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 | 204,641,045 | |
| -1 | -204,641,045 |
Now, we try dividing 204,641,045 by 3:
204,641,045 ÷ 3 = 68,213,681.6667
If the quotient is a whole number, then 3 and 68,213,681.6667 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 | 204,641,045 | |
| -1 | -204,641,045 |
Let's try dividing by 4:
204,641,045 ÷ 4 = 51,160,261.25
If the quotient is a whole number, then 4 and 51,160,261.25 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 | 204,641,045 | |
| -1 | 204,641,045 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 41 | 205 | 287 | 1,435 | 142,607 | 713,035 | 998,249 | 4,991,245 | 5,846,887 | 29,234,435 | 40,928,209 | 204,641,045 |
| -1 | -5 | -7 | -35 | -41 | -205 | -287 | -1,435 | -142,607 | -713,035 | -998,249 | -4,991,245 | -5,846,887 | -29,234,435 | -40,928,209 | -204,641,045 |
