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 404,212,417, 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 | 404,212,417 | |
| -1 | -404,212,417 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 404,212,417.
Example:
1 x 404,212,417 = 404,212,417
and
-1 x -404,212,417 = 404,212,417
Notice both answers equal 404,212,417
With that explanation out of the way, let's continue. Next, we take the number 404,212,417 and divide it by 2:
404,212,417 ÷ 2 = 202,106,208.5
If the quotient is a whole number, then 2 and 202,106,208.5 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 | 404,212,417 | |
| -1 | -404,212,417 |
Now, we try dividing 404,212,417 by 3:
404,212,417 ÷ 3 = 134,737,472.3333
If the quotient is a whole number, then 3 and 134,737,472.3333 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 | 404,212,417 | |
| -1 | -404,212,417 |
Let's try dividing by 4:
404,212,417 ÷ 4 = 101,053,104.25
If the quotient is a whole number, then 4 and 101,053,104.25 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 | 404,212,417 | |
| -1 | 404,212,417 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 49 | 119 | 139 | 833 | 973 | 2,363 | 3,491 | 6,811 | 16,541 | 24,437 | 59,347 | 115,787 | 171,059 | 415,429 | 485,249 | 2,908,003 | 3,396,743 | 8,249,233 | 23,777,201 | 57,744,631 | 404,212,417 |
| -1 | -7 | -17 | -49 | -119 | -139 | -833 | -973 | -2,363 | -3,491 | -6,811 | -16,541 | -24,437 | -59,347 | -115,787 | -171,059 | -415,429 | -485,249 | -2,908,003 | -3,396,743 | -8,249,233 | -23,777,201 | -57,744,631 | -404,212,417 |
