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 32,012,305, 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 | 32,012,305 | |
| -1 | -32,012,305 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 32,012,305.
Example:
1 x 32,012,305 = 32,012,305
and
-1 x -32,012,305 = 32,012,305
Notice both answers equal 32,012,305
With that explanation out of the way, let's continue. Next, we take the number 32,012,305 and divide it by 2:
32,012,305 ÷ 2 = 16,006,152.5
If the quotient is a whole number, then 2 and 16,006,152.5 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 | 32,012,305 | |
| -1 | -32,012,305 |
Now, we try dividing 32,012,305 by 3:
32,012,305 ÷ 3 = 10,670,768.3333
If the quotient is a whole number, then 3 and 10,670,768.3333 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 | 32,012,305 | |
| -1 | -32,012,305 |
Let's try dividing by 4:
32,012,305 ÷ 4 = 8,003,076.25
If the quotient is a whole number, then 4 and 8,003,076.25 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 | 32,012,305 | |
| -1 | 32,012,305 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 31 | 65 | 155 | 403 | 2,015 | 15,887 | 79,435 | 206,531 | 492,497 | 1,032,655 | 2,462,485 | 6,402,461 | 32,012,305 |
| -1 | -5 | -13 | -31 | -65 | -155 | -403 | -2,015 | -15,887 | -79,435 | -206,531 | -492,497 | -1,032,655 | -2,462,485 | -6,402,461 | -32,012,305 |
