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 6,875,375, 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 | 6,875,375 | |
| -1 | -6,875,375 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 6,875,375.
Example:
1 x 6,875,375 = 6,875,375
and
-1 x -6,875,375 = 6,875,375
Notice both answers equal 6,875,375
With that explanation out of the way, let's continue. Next, we take the number 6,875,375 and divide it by 2:
6,875,375 ÷ 2 = 3,437,687.5
If the quotient is a whole number, then 2 and 3,437,687.5 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 | 6,875,375 | |
| -1 | -6,875,375 |
Now, we try dividing 6,875,375 by 3:
6,875,375 ÷ 3 = 2,291,791.6667
If the quotient is a whole number, then 3 and 2,291,791.6667 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 | 6,875,375 | |
| -1 | -6,875,375 |
Let's try dividing by 4:
6,875,375 ÷ 4 = 1,718,843.75
If the quotient is a whole number, then 4 and 1,718,843.75 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 | 6,875,375 | |
| -1 | 6,875,375 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 65 | 125 | 325 | 1,625 | 4,231 | 21,155 | 55,003 | 105,775 | 275,015 | 528,875 | 1,375,075 | 6,875,375 |
| -1 | -5 | -13 | -25 | -65 | -125 | -325 | -1,625 | -4,231 | -21,155 | -55,003 | -105,775 | -275,015 | -528,875 | -1,375,075 | -6,875,375 |
