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 31,336,591, 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 | 31,336,591 | |
| -1 | -31,336,591 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 31,336,591.
Example:
1 x 31,336,591 = 31,336,591
and
-1 x -31,336,591 = 31,336,591
Notice both answers equal 31,336,591
With that explanation out of the way, let's continue. Next, we take the number 31,336,591 and divide it by 2:
31,336,591 ÷ 2 = 15,668,295.5
If the quotient is a whole number, then 2 and 15,668,295.5 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 | 31,336,591 | |
| -1 | -31,336,591 |
Now, we try dividing 31,336,591 by 3:
31,336,591 ÷ 3 = 10,445,530.3333
If the quotient is a whole number, then 3 and 10,445,530.3333 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 | 31,336,591 | |
| -1 | -31,336,591 |
Let's try dividing by 4:
31,336,591 ÷ 4 = 7,834,147.75
If the quotient is a whole number, then 4 and 7,834,147.75 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 | 31,336,591 | |
| -1 | 31,336,591 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 143 | 419 | 523 | 4,609 | 5,447 | 5,753 | 6,799 | 59,917 | 74,789 | 219,137 | 2,410,507 | 2,848,781 | 31,336,591 |
| -1 | -11 | -13 | -143 | -419 | -523 | -4,609 | -5,447 | -5,753 | -6,799 | -59,917 | -74,789 | -219,137 | -2,410,507 | -2,848,781 | -31,336,591 |
