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 32,055,755, 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 | 32,055,755 | |
| -1 | -32,055,755 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 32,055,755.
Example:
1 x 32,055,755 = 32,055,755
and
-1 x -32,055,755 = 32,055,755
Notice both answers equal 32,055,755
With that explanation out of the way, let's continue. Next, we take the number 32,055,755 and divide it by 2:
32,055,755 ÷ 2 = 16,027,877.5
If the quotient is a whole number, then 2 and 16,027,877.5 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 | 32,055,755 | |
| -1 | -32,055,755 |
Now, we try dividing 32,055,755 by 3:
32,055,755 ÷ 3 = 10,685,251.6667
If the quotient is a whole number, then 3 and 10,685,251.6667 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 | 32,055,755 | |
| -1 | -32,055,755 |
Let's try dividing by 4:
32,055,755 ÷ 4 = 8,013,938.75
If the quotient is a whole number, then 4 and 8,013,938.75 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 | 32,055,755 | |
| -1 | 32,055,755 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 263 | 1,283 | 1,315 | 4,997 | 6,415 | 24,377 | 24,985 | 121,885 | 337,429 | 1,687,145 | 6,411,151 | 32,055,755 |
| -1 | -5 | -19 | -95 | -263 | -1,283 | -1,315 | -4,997 | -6,415 | -24,377 | -24,985 | -121,885 | -337,429 | -1,687,145 | -6,411,151 | -32,055,755 |
