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 8,431,375, 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 | 8,431,375 | |
| -1 | -8,431,375 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,431,375.
Example:
1 x 8,431,375 = 8,431,375
and
-1 x -8,431,375 = 8,431,375
Notice both answers equal 8,431,375
With that explanation out of the way, let's continue. Next, we take the number 8,431,375 and divide it by 2:
8,431,375 ÷ 2 = 4,215,687.5
If the quotient is a whole number, then 2 and 4,215,687.5 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 | 8,431,375 | |
| -1 | -8,431,375 |
Now, we try dividing 8,431,375 by 3:
8,431,375 ÷ 3 = 2,810,458.3333
If the quotient is a whole number, then 3 and 2,810,458.3333 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 | 8,431,375 | |
| -1 | -8,431,375 |
Let's try dividing by 4:
8,431,375 ÷ 4 = 2,107,843.75
If the quotient is a whole number, then 4 and 2,107,843.75 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 | 8,431,375 | |
| -1 | 8,431,375 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 37 | 125 | 185 | 925 | 1,823 | 4,625 | 9,115 | 45,575 | 67,451 | 227,875 | 337,255 | 1,686,275 | 8,431,375 |
| -1 | -5 | -25 | -37 | -125 | -185 | -925 | -1,823 | -4,625 | -9,115 | -45,575 | -67,451 | -227,875 | -337,255 | -1,686,275 | -8,431,375 |
