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 204,024,223, 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 | 204,024,223 | |
| -1 | -204,024,223 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 204,024,223.
Example:
1 x 204,024,223 = 204,024,223
and
-1 x -204,024,223 = 204,024,223
Notice both answers equal 204,024,223
With that explanation out of the way, let's continue. Next, we take the number 204,024,223 and divide it by 2:
204,024,223 ÷ 2 = 102,012,111.5
If the quotient is a whole number, then 2 and 102,012,111.5 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 | 204,024,223 | |
| -1 | -204,024,223 |
Now, we try dividing 204,024,223 by 3:
204,024,223 ÷ 3 = 68,008,074.3333
If the quotient is a whole number, then 3 and 68,008,074.3333 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 | 204,024,223 | |
| -1 | -204,024,223 |
Let's try dividing by 4:
204,024,223 ÷ 4 = 51,006,055.75
If the quotient is a whole number, then 4 and 51,006,055.75 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 | 204,024,223 | |
| -1 | 204,024,223 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 89 | 247 | 1,157 | 1,691 | 9,281 | 21,983 | 120,653 | 176,339 | 826,009 | 2,292,407 | 10,738,117 | 15,694,171 | 204,024,223 |
| -1 | -13 | -19 | -89 | -247 | -1,157 | -1,691 | -9,281 | -21,983 | -120,653 | -176,339 | -826,009 | -2,292,407 | -10,738,117 | -15,694,171 | -204,024,223 |
