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 412,001,447, 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 | 412,001,447 | |
| -1 | -412,001,447 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 412,001,447.
Example:
1 x 412,001,447 = 412,001,447
and
-1 x -412,001,447 = 412,001,447
Notice both answers equal 412,001,447
With that explanation out of the way, let's continue. Next, we take the number 412,001,447 and divide it by 2:
412,001,447 ÷ 2 = 206,000,723.5
If the quotient is a whole number, then 2 and 206,000,723.5 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 | 412,001,447 | |
| -1 | -412,001,447 |
Now, we try dividing 412,001,447 by 3:
412,001,447 ÷ 3 = 137,333,815.6667
If the quotient is a whole number, then 3 and 137,333,815.6667 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 | 412,001,447 | |
| -1 | -412,001,447 |
Let's try dividing by 4:
412,001,447 ÷ 4 = 103,000,361.75
If the quotient is a whole number, then 4 and 103,000,361.75 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 | 412,001,447 | |
| -1 | 412,001,447 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 43 | 143 | 473 | 559 | 6,149 | 67,003 | 737,033 | 871,039 | 2,881,129 | 9,581,429 | 31,692,419 | 37,454,677 | 412,001,447 |
| -1 | -11 | -13 | -43 | -143 | -473 | -559 | -6,149 | -67,003 | -737,033 | -871,039 | -2,881,129 | -9,581,429 | -31,692,419 | -37,454,677 | -412,001,447 |
