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 31,083,535, 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 | 31,083,535 | |
| -1 | -31,083,535 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 31,083,535.
Example:
1 x 31,083,535 = 31,083,535
and
-1 x -31,083,535 = 31,083,535
Notice both answers equal 31,083,535
With that explanation out of the way, let's continue. Next, we take the number 31,083,535 and divide it by 2:
31,083,535 ÷ 2 = 15,541,767.5
If the quotient is a whole number, then 2 and 15,541,767.5 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 | 31,083,535 | |
| -1 | -31,083,535 |
Now, we try dividing 31,083,535 by 3:
31,083,535 ÷ 3 = 10,361,178.3333
If the quotient is a whole number, then 3 and 10,361,178.3333 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 | 31,083,535 | |
| -1 | -31,083,535 |
Let's try dividing by 4:
31,083,535 ÷ 4 = 7,770,883.75
If the quotient is a whole number, then 4 and 7,770,883.75 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 | 31,083,535 | |
| -1 | 31,083,535 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 41 | 205 | 287 | 1,435 | 21,661 | 108,305 | 151,627 | 758,135 | 888,101 | 4,440,505 | 6,216,707 | 31,083,535 |
| -1 | -5 | -7 | -35 | -41 | -205 | -287 | -1,435 | -21,661 | -108,305 | -151,627 | -758,135 | -888,101 | -4,440,505 | -6,216,707 | -31,083,535 |
