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 8,195,125, 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 | 8,195,125 | |
| -1 | -8,195,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,195,125.
Example:
1 x 8,195,125 = 8,195,125
and
-1 x -8,195,125 = 8,195,125
Notice both answers equal 8,195,125
With that explanation out of the way, let's continue. Next, we take the number 8,195,125 and divide it by 2:
8,195,125 ÷ 2 = 4,097,562.5
If the quotient is a whole number, then 2 and 4,097,562.5 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 | 8,195,125 | |
| -1 | -8,195,125 |
Now, we try dividing 8,195,125 by 3:
8,195,125 ÷ 3 = 2,731,708.3333
If the quotient is a whole number, then 3 and 2,731,708.3333 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 | 8,195,125 | |
| -1 | -8,195,125 |
Let's try dividing by 4:
8,195,125 ÷ 4 = 2,048,781.25
If the quotient is a whole number, then 4 and 2,048,781.25 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 | 8,195,125 | |
| -1 | 8,195,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 53 | 125 | 265 | 1,237 | 1,325 | 6,185 | 6,625 | 30,925 | 65,561 | 154,625 | 327,805 | 1,639,025 | 8,195,125 |
| -1 | -5 | -25 | -53 | -125 | -265 | -1,237 | -1,325 | -6,185 | -6,625 | -30,925 | -65,561 | -154,625 | -327,805 | -1,639,025 | -8,195,125 |
