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 12,530,329, 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 | 12,530,329 | |
| -1 | -12,530,329 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,530,329.
Example:
1 x 12,530,329 = 12,530,329
and
-1 x -12,530,329 = 12,530,329
Notice both answers equal 12,530,329
With that explanation out of the way, let's continue. Next, we take the number 12,530,329 and divide it by 2:
12,530,329 ÷ 2 = 6,265,164.5
If the quotient is a whole number, then 2 and 6,265,164.5 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 | 12,530,329 | |
| -1 | -12,530,329 |
Now, we try dividing 12,530,329 by 3:
12,530,329 ÷ 3 = 4,176,776.3333
If the quotient is a whole number, then 3 and 4,176,776.3333 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 | 12,530,329 | |
| -1 | -12,530,329 |
Let's try dividing by 4:
12,530,329 ÷ 4 = 3,132,582.25
If the quotient is a whole number, then 4 and 3,132,582.25 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 | 12,530,329 | |
| -1 | 12,530,329 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 43 | 49 | 133 | 301 | 313 | 817 | 931 | 2,107 | 2,191 | 5,719 | 5,947 | 13,459 | 15,337 | 40,033 | 41,629 | 94,213 | 255,721 | 291,403 | 659,491 | 1,790,047 | 12,530,329 |
| -1 | -7 | -19 | -43 | -49 | -133 | -301 | -313 | -817 | -931 | -2,107 | -2,191 | -5,719 | -5,947 | -13,459 | -15,337 | -40,033 | -41,629 | -94,213 | -255,721 | -291,403 | -659,491 | -1,790,047 | -12,530,329 |
