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 12,002,171, 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 | 12,002,171 | |
| -1 | -12,002,171 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,002,171.
Example:
1 x 12,002,171 = 12,002,171
and
-1 x -12,002,171 = 12,002,171
Notice both answers equal 12,002,171
With that explanation out of the way, let's continue. Next, we take the number 12,002,171 and divide it by 2:
12,002,171 ÷ 2 = 6,001,085.5
If the quotient is a whole number, then 2 and 6,001,085.5 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 | 12,002,171 | |
| -1 | -12,002,171 |
Now, we try dividing 12,002,171 by 3:
12,002,171 ÷ 3 = 4,000,723.6667
If the quotient is a whole number, then 3 and 4,000,723.6667 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 | 12,002,171 | |
| -1 | -12,002,171 |
Let's try dividing by 4:
12,002,171 ÷ 4 = 3,000,542.75
If the quotient is a whole number, then 4 and 3,000,542.75 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 | 12,002,171 | |
| -1 | 12,002,171 |
If you did it right, you will end up with this table:
| 1 | 37 | 227 | 1,429 | 8,399 | 52,873 | 324,383 | 12,002,171 |
| -1 | -37 | -227 | -1,429 | -8,399 | -52,873 | -324,383 | -12,002,171 |
