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 416,605,355, 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 | 416,605,355 | |
| -1 | -416,605,355 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 416,605,355.
Example:
1 x 416,605,355 = 416,605,355
and
-1 x -416,605,355 = 416,605,355
Notice both answers equal 416,605,355
With that explanation out of the way, let's continue. Next, we take the number 416,605,355 and divide it by 2:
416,605,355 ÷ 2 = 208,302,677.5
If the quotient is a whole number, then 2 and 208,302,677.5 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 | 416,605,355 | |
| -1 | -416,605,355 |
Now, we try dividing 416,605,355 by 3:
416,605,355 ÷ 3 = 138,868,451.6667
If the quotient is a whole number, then 3 and 138,868,451.6667 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 | 416,605,355 | |
| -1 | -416,605,355 |
Let's try dividing by 4:
416,605,355 ÷ 4 = 104,151,338.75
If the quotient is a whole number, then 4 and 104,151,338.75 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 | 416,605,355 | |
| -1 | 416,605,355 |
If you did it right, you will end up with this table:
| 1 | 5 | 137 | 409 | 685 | 1,487 | 2,045 | 7,435 | 56,033 | 203,719 | 280,165 | 608,183 | 1,018,595 | 3,040,915 | 83,321,071 | 416,605,355 |
| -1 | -5 | -137 | -409 | -685 | -1,487 | -2,045 | -7,435 | -56,033 | -203,719 | -280,165 | -608,183 | -1,018,595 | -3,040,915 | -83,321,071 | -416,605,355 |
