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 12,025,117, 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 | 12,025,117 | |
| -1 | -12,025,117 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,025,117.
Example:
1 x 12,025,117 = 12,025,117
and
-1 x -12,025,117 = 12,025,117
Notice both answers equal 12,025,117
With that explanation out of the way, let's continue. Next, we take the number 12,025,117 and divide it by 2:
12,025,117 ÷ 2 = 6,012,558.5
If the quotient is a whole number, then 2 and 6,012,558.5 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 | 12,025,117 | |
| -1 | -12,025,117 |
Now, we try dividing 12,025,117 by 3:
12,025,117 ÷ 3 = 4,008,372.3333
If the quotient is a whole number, then 3 and 4,008,372.3333 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 | 12,025,117 | |
| -1 | -12,025,117 |
Let's try dividing by 4:
12,025,117 ÷ 4 = 3,006,279.25
If the quotient is a whole number, then 4 and 3,006,279.25 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 | 12,025,117 | |
| -1 | 12,025,117 |
If you did it right, you will end up with this table:
| 1 | 13 | 31 | 53 | 403 | 563 | 689 | 1,643 | 7,319 | 17,453 | 21,359 | 29,839 | 226,889 | 387,907 | 925,009 | 12,025,117 |
| -1 | -13 | -31 | -53 | -403 | -563 | -689 | -1,643 | -7,319 | -17,453 | -21,359 | -29,839 | -226,889 | -387,907 | -925,009 | -12,025,117 |
