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 413,134,255, 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 | 413,134,255 | |
| -1 | -413,134,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 413,134,255.
Example:
1 x 413,134,255 = 413,134,255
and
-1 x -413,134,255 = 413,134,255
Notice both answers equal 413,134,255
With that explanation out of the way, let's continue. Next, we take the number 413,134,255 and divide it by 2:
413,134,255 ÷ 2 = 206,567,127.5
If the quotient is a whole number, then 2 and 206,567,127.5 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 | 413,134,255 | |
| -1 | -413,134,255 |
Now, we try dividing 413,134,255 by 3:
413,134,255 ÷ 3 = 137,711,418.3333
If the quotient is a whole number, then 3 and 137,711,418.3333 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 | 413,134,255 | |
| -1 | -413,134,255 |
Let's try dividing by 4:
413,134,255 ÷ 4 = 103,283,563.75
If the quotient is a whole number, then 4 and 103,283,563.75 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 | 413,134,255 | |
| -1 | 413,134,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 739 | 3,695 | 6,577 | 12,563 | 32,885 | 62,815 | 111,809 | 559,045 | 4,860,403 | 24,302,015 | 82,626,851 | 413,134,255 |
| -1 | -5 | -17 | -85 | -739 | -3,695 | -6,577 | -12,563 | -32,885 | -62,815 | -111,809 | -559,045 | -4,860,403 | -24,302,015 | -82,626,851 | -413,134,255 |
