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 32,876,123, 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 | 32,876,123 | |
| -1 | -32,876,123 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 32,876,123.
Example:
1 x 32,876,123 = 32,876,123
and
-1 x -32,876,123 = 32,876,123
Notice both answers equal 32,876,123
With that explanation out of the way, let's continue. Next, we take the number 32,876,123 and divide it by 2:
32,876,123 ÷ 2 = 16,438,061.5
If the quotient is a whole number, then 2 and 16,438,061.5 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 | 32,876,123 | |
| -1 | -32,876,123 |
Now, we try dividing 32,876,123 by 3:
32,876,123 ÷ 3 = 10,958,707.6667
If the quotient is a whole number, then 3 and 10,958,707.6667 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 | 32,876,123 | |
| -1 | -32,876,123 |
Let's try dividing by 4:
32,876,123 ÷ 4 = 8,219,030.75
If the quotient is a whole number, then 4 and 8,219,030.75 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 | 32,876,123 | |
| -1 | 32,876,123 |
If you did it right, you will end up with this table:
| 1 | 7 | 43 | 239 | 301 | 457 | 1,673 | 3,199 | 10,277 | 19,651 | 71,939 | 109,223 | 137,557 | 764,561 | 4,696,589 | 32,876,123 |
| -1 | -7 | -43 | -239 | -301 | -457 | -1,673 | -3,199 | -10,277 | -19,651 | -71,939 | -109,223 | -137,557 | -764,561 | -4,696,589 | -32,876,123 |
