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 413,112,223, 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 | 413,112,223 | |
| -1 | -413,112,223 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 413,112,223.
Example:
1 x 413,112,223 = 413,112,223
and
-1 x -413,112,223 = 413,112,223
Notice both answers equal 413,112,223
With that explanation out of the way, let's continue. Next, we take the number 413,112,223 and divide it by 2:
413,112,223 ÷ 2 = 206,556,111.5
If the quotient is a whole number, then 2 and 206,556,111.5 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 | 413,112,223 | |
| -1 | -413,112,223 |
Now, we try dividing 413,112,223 by 3:
413,112,223 ÷ 3 = 137,704,074.3333
If the quotient is a whole number, then 3 and 137,704,074.3333 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 | 413,112,223 | |
| -1 | -413,112,223 |
Let's try dividing by 4:
413,112,223 ÷ 4 = 103,278,055.75
If the quotient is a whole number, then 4 and 103,278,055.75 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 | 413,112,223 | |
| -1 | 413,112,223 |
If you did it right, you will end up with this table:
| 1 | 17 | 23 | 43 | 391 | 731 | 989 | 16,813 | 24,571 | 417,707 | 565,133 | 1,056,553 | 9,607,261 | 17,961,401 | 24,300,719 | 413,112,223 |
| -1 | -17 | -23 | -43 | -391 | -731 | -989 | -16,813 | -24,571 | -417,707 | -565,133 | -1,056,553 | -9,607,261 | -17,961,401 | -24,300,719 | -413,112,223 |
