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 31,833,685, 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 | 31,833,685 | |
| -1 | -31,833,685 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 31,833,685.
Example:
1 x 31,833,685 = 31,833,685
and
-1 x -31,833,685 = 31,833,685
Notice both answers equal 31,833,685
With that explanation out of the way, let's continue. Next, we take the number 31,833,685 and divide it by 2:
31,833,685 ÷ 2 = 15,916,842.5
If the quotient is a whole number, then 2 and 15,916,842.5 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 | 31,833,685 | |
| -1 | -31,833,685 |
Now, we try dividing 31,833,685 by 3:
31,833,685 ÷ 3 = 10,611,228.3333
If the quotient is a whole number, then 3 and 10,611,228.3333 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 | 31,833,685 | |
| -1 | -31,833,685 |
Let's try dividing by 4:
31,833,685 ÷ 4 = 7,958,421.25
If the quotient is a whole number, then 4 and 7,958,421.25 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 | 31,833,685 | |
| -1 | 31,833,685 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 101 | 169 | 373 | 505 | 845 | 1,313 | 1,865 | 4,849 | 6,565 | 17,069 | 24,245 | 37,673 | 63,037 | 85,345 | 188,365 | 315,185 | 489,749 | 2,448,745 | 6,366,737 | 31,833,685 |
| -1 | -5 | -13 | -65 | -101 | -169 | -373 | -505 | -845 | -1,313 | -1,865 | -4,849 | -6,565 | -17,069 | -24,245 | -37,673 | -63,037 | -85,345 | -188,365 | -315,185 | -489,749 | -2,448,745 | -6,366,737 | -31,833,685 |
