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 10,807,325, 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 | 10,807,325 | |
| -1 | -10,807,325 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,807,325.
Example:
1 x 10,807,325 = 10,807,325
and
-1 x -10,807,325 = 10,807,325
Notice both answers equal 10,807,325
With that explanation out of the way, let's continue. Next, we take the number 10,807,325 and divide it by 2:
10,807,325 ÷ 2 = 5,403,662.5
If the quotient is a whole number, then 2 and 5,403,662.5 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 | 10,807,325 | |
| -1 | -10,807,325 |
Now, we try dividing 10,807,325 by 3:
10,807,325 ÷ 3 = 3,602,441.6667
If the quotient is a whole number, then 3 and 3,602,441.6667 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 | 10,807,325 | |
| -1 | -10,807,325 |
Let's try dividing by 4:
10,807,325 ÷ 4 = 2,701,831.25
If the quotient is a whole number, then 4 and 2,701,831.25 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 | 10,807,325 | |
| -1 | 10,807,325 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 59 | 85 | 295 | 425 | 431 | 1,003 | 1,475 | 2,155 | 5,015 | 7,327 | 10,775 | 25,075 | 25,429 | 36,635 | 127,145 | 183,175 | 432,293 | 635,725 | 2,161,465 | 10,807,325 |
| -1 | -5 | -17 | -25 | -59 | -85 | -295 | -425 | -431 | -1,003 | -1,475 | -2,155 | -5,015 | -7,327 | -10,775 | -25,075 | -25,429 | -36,635 | -127,145 | -183,175 | -432,293 | -635,725 | -2,161,465 | -10,807,325 |
