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 32,002,415, 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 | 32,002,415 | |
| -1 | -32,002,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 32,002,415.
Example:
1 x 32,002,415 = 32,002,415
and
-1 x -32,002,415 = 32,002,415
Notice both answers equal 32,002,415
With that explanation out of the way, let's continue. Next, we take the number 32,002,415 and divide it by 2:
32,002,415 ÷ 2 = 16,001,207.5
If the quotient is a whole number, then 2 and 16,001,207.5 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 | 32,002,415 | |
| -1 | -32,002,415 |
Now, we try dividing 32,002,415 by 3:
32,002,415 ÷ 3 = 10,667,471.6667
If the quotient is a whole number, then 3 and 10,667,471.6667 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 | 32,002,415 | |
| -1 | -32,002,415 |
Let's try dividing by 4:
32,002,415 ÷ 4 = 8,000,603.75
If the quotient is a whole number, then 4 and 8,000,603.75 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 | 32,002,415 | |
| -1 | 32,002,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 289 | 1,445 | 22,147 | 110,735 | 376,499 | 1,882,495 | 6,400,483 | 32,002,415 |
| -1 | -5 | -17 | -85 | -289 | -1,445 | -22,147 | -110,735 | -376,499 | -1,882,495 | -6,400,483 | -32,002,415 |
