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 31,833,683, 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 | 31,833,683 | |
| -1 | -31,833,683 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 31,833,683.
Example:
1 x 31,833,683 = 31,833,683
and
-1 x -31,833,683 = 31,833,683
Notice both answers equal 31,833,683
With that explanation out of the way, let's continue. Next, we take the number 31,833,683 and divide it by 2:
31,833,683 ÷ 2 = 15,916,841.5
If the quotient is a whole number, then 2 and 15,916,841.5 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 | 31,833,683 | |
| -1 | -31,833,683 |
Now, we try dividing 31,833,683 by 3:
31,833,683 ÷ 3 = 10,611,227.6667
If the quotient is a whole number, then 3 and 10,611,227.6667 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 | 31,833,683 | |
| -1 | -31,833,683 |
Let's try dividing by 4:
31,833,683 ÷ 4 = 7,958,420.75
If the quotient is a whole number, then 4 and 7,958,420.75 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 | 31,833,683 | |
| -1 | 31,833,683 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 31 | 49 | 133 | 217 | 589 | 931 | 1,103 | 1,519 | 4,123 | 7,721 | 20,957 | 28,861 | 34,193 | 54,047 | 146,699 | 239,351 | 649,667 | 1,026,893 | 1,675,457 | 4,547,669 | 31,833,683 |
| -1 | -7 | -19 | -31 | -49 | -133 | -217 | -589 | -931 | -1,103 | -1,519 | -4,123 | -7,721 | -20,957 | -28,861 | -34,193 | -54,047 | -146,699 | -239,351 | -649,667 | -1,026,893 | -1,675,457 | -4,547,669 | -31,833,683 |
