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 434,164,415, 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 | 434,164,415 | |
| -1 | -434,164,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 434,164,415.
Example:
1 x 434,164,415 = 434,164,415
and
-1 x -434,164,415 = 434,164,415
Notice both answers equal 434,164,415
With that explanation out of the way, let's continue. Next, we take the number 434,164,415 and divide it by 2:
434,164,415 ÷ 2 = 217,082,207.5
If the quotient is a whole number, then 2 and 217,082,207.5 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 | 434,164,415 | |
| -1 | -434,164,415 |
Now, we try dividing 434,164,415 by 3:
434,164,415 ÷ 3 = 144,721,471.6667
If the quotient is a whole number, then 3 and 144,721,471.6667 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 | 434,164,415 | |
| -1 | -434,164,415 |
Let's try dividing by 4:
434,164,415 ÷ 4 = 108,541,103.75
If the quotient is a whole number, then 4 and 108,541,103.75 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 | 434,164,415 | |
| -1 | 434,164,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 139 | 439 | 695 | 1,423 | 2,195 | 7,115 | 61,021 | 197,797 | 305,105 | 624,697 | 988,985 | 3,123,485 | 86,832,883 | 434,164,415 |
| -1 | -5 | -139 | -439 | -695 | -1,423 | -2,195 | -7,115 | -61,021 | -197,797 | -305,105 | -624,697 | -988,985 | -3,123,485 | -86,832,883 | -434,164,415 |
