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 12,935,875, 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 | 12,935,875 | |
| -1 | -12,935,875 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,935,875.
Example:
1 x 12,935,875 = 12,935,875
and
-1 x -12,935,875 = 12,935,875
Notice both answers equal 12,935,875
With that explanation out of the way, let's continue. Next, we take the number 12,935,875 and divide it by 2:
12,935,875 ÷ 2 = 6,467,937.5
If the quotient is a whole number, then 2 and 6,467,937.5 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 | 12,935,875 | |
| -1 | -12,935,875 |
Now, we try dividing 12,935,875 by 3:
12,935,875 ÷ 3 = 4,311,958.3333
If the quotient is a whole number, then 3 and 4,311,958.3333 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 | 12,935,875 | |
| -1 | -12,935,875 |
Let's try dividing by 4:
12,935,875 ÷ 4 = 3,233,968.75
If the quotient is a whole number, then 4 and 3,233,968.75 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 | 12,935,875 | |
| -1 | 12,935,875 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 125 | 239 | 433 | 1,195 | 2,165 | 5,975 | 10,825 | 29,875 | 54,125 | 103,487 | 517,435 | 2,587,175 | 12,935,875 |
| -1 | -5 | -25 | -125 | -239 | -433 | -1,195 | -2,165 | -5,975 | -10,825 | -29,875 | -54,125 | -103,487 | -517,435 | -2,587,175 | -12,935,875 |
