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 83,339,417, 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 | 83,339,417 | |
| -1 | -83,339,417 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 83,339,417.
Example:
1 x 83,339,417 = 83,339,417
and
-1 x -83,339,417 = 83,339,417
Notice both answers equal 83,339,417
With that explanation out of the way, let's continue. Next, we take the number 83,339,417 and divide it by 2:
83,339,417 ÷ 2 = 41,669,708.5
If the quotient is a whole number, then 2 and 41,669,708.5 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 | 83,339,417 | |
| -1 | -83,339,417 |
Now, we try dividing 83,339,417 by 3:
83,339,417 ÷ 3 = 27,779,805.6667
If the quotient is a whole number, then 3 and 27,779,805.6667 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 | 83,339,417 | |
| -1 | -83,339,417 |
Let's try dividing by 4:
83,339,417 ÷ 4 = 20,834,854.25
If the quotient is a whole number, then 4 and 20,834,854.25 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 | 83,339,417 | |
| -1 | 83,339,417 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 203 | 353 | 1,163 | 2,471 | 8,141 | 10,237 | 33,727 | 71,659 | 236,089 | 410,539 | 2,873,773 | 11,905,631 | 83,339,417 |
| -1 | -7 | -29 | -203 | -353 | -1,163 | -2,471 | -8,141 | -10,237 | -33,727 | -71,659 | -236,089 | -410,539 | -2,873,773 | -11,905,631 | -83,339,417 |
