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 12,853,375, 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 | 12,853,375 | |
| -1 | -12,853,375 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,853,375.
Example:
1 x 12,853,375 = 12,853,375
and
-1 x -12,853,375 = 12,853,375
Notice both answers equal 12,853,375
With that explanation out of the way, let's continue. Next, we take the number 12,853,375 and divide it by 2:
12,853,375 ÷ 2 = 6,426,687.5
If the quotient is a whole number, then 2 and 6,426,687.5 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 | 12,853,375 | |
| -1 | -12,853,375 |
Now, we try dividing 12,853,375 by 3:
12,853,375 ÷ 3 = 4,284,458.3333
If the quotient is a whole number, then 3 and 4,284,458.3333 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 | 12,853,375 | |
| -1 | -12,853,375 |
Let's try dividing by 4:
12,853,375 ÷ 4 = 3,213,343.75
If the quotient is a whole number, then 4 and 3,213,343.75 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 | 12,853,375 | |
| -1 | 12,853,375 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 31 | 107 | 125 | 155 | 535 | 775 | 961 | 2,675 | 3,317 | 3,875 | 4,805 | 13,375 | 16,585 | 24,025 | 82,925 | 102,827 | 120,125 | 414,625 | 514,135 | 2,570,675 | 12,853,375 |
| -1 | -5 | -25 | -31 | -107 | -125 | -155 | -535 | -775 | -961 | -2,675 | -3,317 | -3,875 | -4,805 | -13,375 | -16,585 | -24,025 | -82,925 | -102,827 | -120,125 | -414,625 | -514,135 | -2,570,675 | -12,853,375 |
