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 31,822,685, 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 | 31,822,685 | |
| -1 | -31,822,685 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 31,822,685.
Example:
1 x 31,822,685 = 31,822,685
and
-1 x -31,822,685 = 31,822,685
Notice both answers equal 31,822,685
With that explanation out of the way, let's continue. Next, we take the number 31,822,685 and divide it by 2:
31,822,685 ÷ 2 = 15,911,342.5
If the quotient is a whole number, then 2 and 15,911,342.5 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 | 31,822,685 | |
| -1 | -31,822,685 |
Now, we try dividing 31,822,685 by 3:
31,822,685 ÷ 3 = 10,607,561.6667
If the quotient is a whole number, then 3 and 10,607,561.6667 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 | 31,822,685 | |
| -1 | -31,822,685 |
Let's try dividing by 4:
31,822,685 ÷ 4 = 7,955,671.25
If the quotient is a whole number, then 4 and 7,955,671.25 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 | 31,822,685 | |
| -1 | 31,822,685 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 167 | 835 | 1,657 | 3,841 | 8,285 | 19,205 | 38,111 | 190,555 | 276,719 | 1,383,595 | 6,364,537 | 31,822,685 |
| -1 | -5 | -23 | -115 | -167 | -835 | -1,657 | -3,841 | -8,285 | -19,205 | -38,111 | -190,555 | -276,719 | -1,383,595 | -6,364,537 | -31,822,685 |
