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 32,166,071, 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 | 32,166,071 | |
| -1 | -32,166,071 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 32,166,071.
Example:
1 x 32,166,071 = 32,166,071
and
-1 x -32,166,071 = 32,166,071
Notice both answers equal 32,166,071
With that explanation out of the way, let's continue. Next, we take the number 32,166,071 and divide it by 2:
32,166,071 ÷ 2 = 16,083,035.5
If the quotient is a whole number, then 2 and 16,083,035.5 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 | 32,166,071 | |
| -1 | -32,166,071 |
Now, we try dividing 32,166,071 by 3:
32,166,071 ÷ 3 = 10,722,023.6667
If the quotient is a whole number, then 3 and 10,722,023.6667 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 | 32,166,071 | |
| -1 | -32,166,071 |
Let's try dividing by 4:
32,166,071 ÷ 4 = 8,041,517.75
If the quotient is a whole number, then 4 and 8,041,517.75 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 | 32,166,071 | |
| -1 | 32,166,071 |
If you did it right, you will end up with this table:
| 1 | 7 | 53 | 277 | 313 | 371 | 1,939 | 2,191 | 14,681 | 16,589 | 86,701 | 102,767 | 116,123 | 606,907 | 4,595,153 | 32,166,071 |
| -1 | -7 | -53 | -277 | -313 | -371 | -1,939 | -2,191 | -14,681 | -16,589 | -86,701 | -102,767 | -116,123 | -606,907 | -4,595,153 | -32,166,071 |
