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 413,320,427, 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 | 413,320,427 | |
| -1 | -413,320,427 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 413,320,427.
Example:
1 x 413,320,427 = 413,320,427
and
-1 x -413,320,427 = 413,320,427
Notice both answers equal 413,320,427
With that explanation out of the way, let's continue. Next, we take the number 413,320,427 and divide it by 2:
413,320,427 ÷ 2 = 206,660,213.5
If the quotient is a whole number, then 2 and 206,660,213.5 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 | 413,320,427 | |
| -1 | -413,320,427 |
Now, we try dividing 413,320,427 by 3:
413,320,427 ÷ 3 = 137,773,475.6667
If the quotient is a whole number, then 3 and 137,773,475.6667 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 | 413,320,427 | |
| -1 | -413,320,427 |
Let's try dividing by 4:
413,320,427 ÷ 4 = 103,330,106.75
If the quotient is a whole number, then 4 and 103,330,106.75 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 | 413,320,427 | |
| -1 | 413,320,427 |
If you did it right, you will end up with this table:
| 1 | 13 | 31 | 169 | 403 | 5,239 | 78,893 | 1,025,609 | 2,445,683 | 13,332,917 | 31,793,879 | 413,320,427 |
| -1 | -13 | -31 | -169 | -403 | -5,239 | -78,893 | -1,025,609 | -2,445,683 | -13,332,917 | -31,793,879 | -413,320,427 |
