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 6,896,015, 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 | 6,896,015 | |
| -1 | -6,896,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 6,896,015.
Example:
1 x 6,896,015 = 6,896,015
and
-1 x -6,896,015 = 6,896,015
Notice both answers equal 6,896,015
With that explanation out of the way, let's continue. Next, we take the number 6,896,015 and divide it by 2:
6,896,015 ÷ 2 = 3,448,007.5
If the quotient is a whole number, then 2 and 3,448,007.5 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 | 6,896,015 | |
| -1 | -6,896,015 |
Now, we try dividing 6,896,015 by 3:
6,896,015 ÷ 3 = 2,298,671.6667
If the quotient is a whole number, then 3 and 2,298,671.6667 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 | 6,896,015 | |
| -1 | -6,896,015 |
Let's try dividing by 4:
6,896,015 ÷ 4 = 1,724,003.75
If the quotient is a whole number, then 4 and 1,724,003.75 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 | 6,896,015 | |
| -1 | 6,896,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 245 | 343 | 1,715 | 4,021 | 20,105 | 28,147 | 140,735 | 197,029 | 985,145 | 1,379,203 | 6,896,015 |
| -1 | -5 | -7 | -35 | -49 | -245 | -343 | -1,715 | -4,021 | -20,105 | -28,147 | -140,735 | -197,029 | -985,145 | -1,379,203 | -6,896,015 |
