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 12,506,065, 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 | 12,506,065 | |
| -1 | -12,506,065 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,506,065.
Example:
1 x 12,506,065 = 12,506,065
and
-1 x -12,506,065 = 12,506,065
Notice both answers equal 12,506,065
With that explanation out of the way, let's continue. Next, we take the number 12,506,065 and divide it by 2:
12,506,065 ÷ 2 = 6,253,032.5
If the quotient is a whole number, then 2 and 6,253,032.5 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 | 12,506,065 | |
| -1 | -12,506,065 |
Now, we try dividing 12,506,065 by 3:
12,506,065 ÷ 3 = 4,168,688.3333
If the quotient is a whole number, then 3 and 4,168,688.3333 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 | 12,506,065 | |
| -1 | -12,506,065 |
Let's try dividing by 4:
12,506,065 ÷ 4 = 3,126,516.25
If the quotient is a whole number, then 4 and 3,126,516.25 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 | 12,506,065 | |
| -1 | 12,506,065 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 13 | 55 | 65 | 143 | 715 | 17,491 | 87,455 | 192,401 | 227,383 | 962,005 | 1,136,915 | 2,501,213 | 12,506,065 |
| -1 | -5 | -11 | -13 | -55 | -65 | -143 | -715 | -17,491 | -87,455 | -192,401 | -227,383 | -962,005 | -1,136,915 | -2,501,213 | -12,506,065 |
