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 31,056,065, 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 | 31,056,065 | |
| -1 | -31,056,065 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 31,056,065.
Example:
1 x 31,056,065 = 31,056,065
and
-1 x -31,056,065 = 31,056,065
Notice both answers equal 31,056,065
With that explanation out of the way, let's continue. Next, we take the number 31,056,065 and divide it by 2:
31,056,065 ÷ 2 = 15,528,032.5
If the quotient is a whole number, then 2 and 15,528,032.5 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 | 31,056,065 | |
| -1 | -31,056,065 |
Now, we try dividing 31,056,065 by 3:
31,056,065 ÷ 3 = 10,352,021.6667
If the quotient is a whole number, then 3 and 10,352,021.6667 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 | 31,056,065 | |
| -1 | -31,056,065 |
Let's try dividing by 4:
31,056,065 ÷ 4 = 7,764,016.25
If the quotient is a whole number, then 4 and 7,764,016.25 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 | 31,056,065 | |
| -1 | 31,056,065 |
If you did it right, you will end up with this table:
| 1 | 5 | 41 | 197 | 205 | 769 | 985 | 3,845 | 8,077 | 31,529 | 40,385 | 151,493 | 157,645 | 757,465 | 6,211,213 | 31,056,065 |
| -1 | -5 | -41 | -197 | -205 | -769 | -985 | -3,845 | -8,077 | -31,529 | -40,385 | -151,493 | -157,645 | -757,465 | -6,211,213 | -31,056,065 |
