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 12,501,035, 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 | 12,501,035 | |
| -1 | -12,501,035 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,501,035.
Example:
1 x 12,501,035 = 12,501,035
and
-1 x -12,501,035 = 12,501,035
Notice both answers equal 12,501,035
With that explanation out of the way, let's continue. Next, we take the number 12,501,035 and divide it by 2:
12,501,035 ÷ 2 = 6,250,517.5
If the quotient is a whole number, then 2 and 6,250,517.5 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 | 12,501,035 | |
| -1 | -12,501,035 |
Now, we try dividing 12,501,035 by 3:
12,501,035 ÷ 3 = 4,167,011.6667
If the quotient is a whole number, then 3 and 4,167,011.6667 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 | 12,501,035 | |
| -1 | -12,501,035 |
Let's try dividing by 4:
12,501,035 ÷ 4 = 3,125,258.75
If the quotient is a whole number, then 4 and 3,125,258.75 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 | 12,501,035 | |
| -1 | 12,501,035 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 61 | 85 | 305 | 1,037 | 2,411 | 5,185 | 12,055 | 40,987 | 147,071 | 204,935 | 735,355 | 2,500,207 | 12,501,035 |
| -1 | -5 | -17 | -61 | -85 | -305 | -1,037 | -2,411 | -5,185 | -12,055 | -40,987 | -147,071 | -204,935 | -735,355 | -2,500,207 | -12,501,035 |
