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 31,023,055, 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 | 31,023,055 | |
| -1 | -31,023,055 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 31,023,055.
Example:
1 x 31,023,055 = 31,023,055
and
-1 x -31,023,055 = 31,023,055
Notice both answers equal 31,023,055
With that explanation out of the way, let's continue. Next, we take the number 31,023,055 and divide it by 2:
31,023,055 ÷ 2 = 15,511,527.5
If the quotient is a whole number, then 2 and 15,511,527.5 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 | 31,023,055 | |
| -1 | -31,023,055 |
Now, we try dividing 31,023,055 by 3:
31,023,055 ÷ 3 = 10,341,018.3333
If the quotient is a whole number, then 3 and 10,341,018.3333 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 | 31,023,055 | |
| -1 | -31,023,055 |
Let's try dividing by 4:
31,023,055 ÷ 4 = 7,755,763.75
If the quotient is a whole number, then 4 and 7,755,763.75 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 | 31,023,055 | |
| -1 | 31,023,055 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 47 | 235 | 329 | 1,645 | 18,859 | 94,295 | 132,013 | 660,065 | 886,373 | 4,431,865 | 6,204,611 | 31,023,055 |
| -1 | -5 | -7 | -35 | -47 | -235 | -329 | -1,645 | -18,859 | -94,295 | -132,013 | -660,065 | -886,373 | -4,431,865 | -6,204,611 | -31,023,055 |
