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 413,211,335, 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 | 413,211,335 | |
| -1 | -413,211,335 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 413,211,335.
Example:
1 x 413,211,335 = 413,211,335
and
-1 x -413,211,335 = 413,211,335
Notice both answers equal 413,211,335
With that explanation out of the way, let's continue. Next, we take the number 413,211,335 and divide it by 2:
413,211,335 ÷ 2 = 206,605,667.5
If the quotient is a whole number, then 2 and 206,605,667.5 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 | 413,211,335 | |
| -1 | -413,211,335 |
Now, we try dividing 413,211,335 by 3:
413,211,335 ÷ 3 = 137,737,111.6667
If the quotient is a whole number, then 3 and 137,737,111.6667 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 | 413,211,335 | |
| -1 | -413,211,335 |
Let's try dividing by 4:
413,211,335 ÷ 4 = 103,302,833.75
If the quotient is a whole number, then 4 and 103,302,833.75 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 | 413,211,335 | |
| -1 | 413,211,335 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 131 | 655 | 2,489 | 12,445 | 33,203 | 166,015 | 630,857 | 3,154,285 | 4,349,593 | 21,747,965 | 82,642,267 | 413,211,335 |
| -1 | -5 | -19 | -95 | -131 | -655 | -2,489 | -12,445 | -33,203 | -166,015 | -630,857 | -3,154,285 | -4,349,593 | -21,747,965 | -82,642,267 | -413,211,335 |
