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 31,336,595, 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 | 31,336,595 | |
| -1 | -31,336,595 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 31,336,595.
Example:
1 x 31,336,595 = 31,336,595
and
-1 x -31,336,595 = 31,336,595
Notice both answers equal 31,336,595
With that explanation out of the way, let's continue. Next, we take the number 31,336,595 and divide it by 2:
31,336,595 ÷ 2 = 15,668,297.5
If the quotient is a whole number, then 2 and 15,668,297.5 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 | 31,336,595 | |
| -1 | -31,336,595 |
Now, we try dividing 31,336,595 by 3:
31,336,595 ÷ 3 = 10,445,531.6667
If the quotient is a whole number, then 3 and 10,445,531.6667 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 | 31,336,595 | |
| -1 | -31,336,595 |
Let's try dividing by 4:
31,336,595 ÷ 4 = 7,834,148.75
If the quotient is a whole number, then 4 and 7,834,148.75 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 | 31,336,595 | |
| -1 | 31,336,595 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 113 | 185 | 565 | 1,499 | 4,181 | 7,495 | 20,905 | 55,463 | 169,387 | 277,315 | 846,935 | 6,267,319 | 31,336,595 |
| -1 | -5 | -37 | -113 | -185 | -565 | -1,499 | -4,181 | -7,495 | -20,905 | -55,463 | -169,387 | -277,315 | -846,935 | -6,267,319 | -31,336,595 |
