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 417,550,439, 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 | 417,550,439 | |
| -1 | -417,550,439 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 417,550,439.
Example:
1 x 417,550,439 = 417,550,439
and
-1 x -417,550,439 = 417,550,439
Notice both answers equal 417,550,439
With that explanation out of the way, let's continue. Next, we take the number 417,550,439 and divide it by 2:
417,550,439 ÷ 2 = 208,775,219.5
If the quotient is a whole number, then 2 and 208,775,219.5 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 | 417,550,439 | |
| -1 | -417,550,439 |
Now, we try dividing 417,550,439 by 3:
417,550,439 ÷ 3 = 139,183,479.6667
If the quotient is a whole number, then 3 and 139,183,479.6667 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 | 417,550,439 | |
| -1 | -417,550,439 |
Let's try dividing by 4:
417,550,439 ÷ 4 = 104,387,609.75
If the quotient is a whole number, then 4 and 104,387,609.75 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 | 417,550,439 | |
| -1 | 417,550,439 |
If you did it right, you will end up with this table:
| 1 | 29 | 31 | 37 | 899 | 1,073 | 1,147 | 12,553 | 33,263 | 364,037 | 389,143 | 464,461 | 11,285,147 | 13,469,369 | 14,398,291 | 417,550,439 |
| -1 | -29 | -31 | -37 | -899 | -1,073 | -1,147 | -12,553 | -33,263 | -364,037 | -389,143 | -464,461 | -11,285,147 | -13,469,369 | -14,398,291 | -417,550,439 |
