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 12,375,965, 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 | 12,375,965 | |
| -1 | -12,375,965 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,375,965.
Example:
1 x 12,375,965 = 12,375,965
and
-1 x -12,375,965 = 12,375,965
Notice both answers equal 12,375,965
With that explanation out of the way, let's continue. Next, we take the number 12,375,965 and divide it by 2:
12,375,965 ÷ 2 = 6,187,982.5
If the quotient is a whole number, then 2 and 6,187,982.5 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 | 12,375,965 | |
| -1 | -12,375,965 |
Now, we try dividing 12,375,965 by 3:
12,375,965 ÷ 3 = 4,125,321.6667
If the quotient is a whole number, then 3 and 4,125,321.6667 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 | 12,375,965 | |
| -1 | -12,375,965 |
Let's try dividing by 4:
12,375,965 ÷ 4 = 3,093,991.25
If the quotient is a whole number, then 4 and 3,093,991.25 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 | 12,375,965 | |
| -1 | 12,375,965 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 103 | 515 | 721 | 3,433 | 3,605 | 17,165 | 24,031 | 120,155 | 353,599 | 1,767,995 | 2,475,193 | 12,375,965 |
| -1 | -5 | -7 | -35 | -103 | -515 | -721 | -3,433 | -3,605 | -17,165 | -24,031 | -120,155 | -353,599 | -1,767,995 | -2,475,193 | -12,375,965 |
