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 32,031,305, 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 | 32,031,305 | |
| -1 | -32,031,305 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 32,031,305.
Example:
1 x 32,031,305 = 32,031,305
and
-1 x -32,031,305 = 32,031,305
Notice both answers equal 32,031,305
With that explanation out of the way, let's continue. Next, we take the number 32,031,305 and divide it by 2:
32,031,305 ÷ 2 = 16,015,652.5
If the quotient is a whole number, then 2 and 16,015,652.5 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 | 32,031,305 | |
| -1 | -32,031,305 |
Now, we try dividing 32,031,305 by 3:
32,031,305 ÷ 3 = 10,677,101.6667
If the quotient is a whole number, then 3 and 10,677,101.6667 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 | 32,031,305 | |
| -1 | -32,031,305 |
Let's try dividing by 4:
32,031,305 ÷ 4 = 8,007,826.25
If the quotient is a whole number, then 4 and 8,007,826.25 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 | 32,031,305 | |
| -1 | 32,031,305 |
If you did it right, you will end up with this table:
| 1 | 5 | 73 | 127 | 365 | 635 | 691 | 3,455 | 9,271 | 46,355 | 50,443 | 87,757 | 252,215 | 438,785 | 6,406,261 | 32,031,305 |
| -1 | -5 | -73 | -127 | -365 | -635 | -691 | -3,455 | -9,271 | -46,355 | -50,443 | -87,757 | -252,215 | -438,785 | -6,406,261 | -32,031,305 |
