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 413,404,663, 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 | 413,404,663 | |
| -1 | -413,404,663 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 413,404,663.
Example:
1 x 413,404,663 = 413,404,663
and
-1 x -413,404,663 = 413,404,663
Notice both answers equal 413,404,663
With that explanation out of the way, let's continue. Next, we take the number 413,404,663 and divide it by 2:
413,404,663 ÷ 2 = 206,702,331.5
If the quotient is a whole number, then 2 and 206,702,331.5 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 | 413,404,663 | |
| -1 | -413,404,663 |
Now, we try dividing 413,404,663 by 3:
413,404,663 ÷ 3 = 137,801,554.3333
If the quotient is a whole number, then 3 and 137,801,554.3333 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 | 413,404,663 | |
| -1 | -413,404,663 |
Let's try dividing by 4:
413,404,663 ÷ 4 = 103,351,165.75
If the quotient is a whole number, then 4 and 103,351,165.75 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 | 413,404,663 | |
| -1 | 413,404,663 |
If you did it right, you will end up with this table:
| 1 | 7 | 37 | 259 | 809 | 1,973 | 5,663 | 13,811 | 29,933 | 73,001 | 209,531 | 511,007 | 1,596,157 | 11,173,099 | 59,057,809 | 413,404,663 |
| -1 | -7 | -37 | -259 | -809 | -1,973 | -5,663 | -13,811 | -29,933 | -73,001 | -209,531 | -511,007 | -1,596,157 | -11,173,099 | -59,057,809 | -413,404,663 |
