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 6,457,825, 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 | 6,457,825 | |
| -1 | -6,457,825 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 6,457,825.
Example:
1 x 6,457,825 = 6,457,825
and
-1 x -6,457,825 = 6,457,825
Notice both answers equal 6,457,825
With that explanation out of the way, let's continue. Next, we take the number 6,457,825 and divide it by 2:
6,457,825 ÷ 2 = 3,228,912.5
If the quotient is a whole number, then 2 and 3,228,912.5 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 | 6,457,825 | |
| -1 | -6,457,825 |
Now, we try dividing 6,457,825 by 3:
6,457,825 ÷ 3 = 2,152,608.3333
If the quotient is a whole number, then 3 and 2,152,608.3333 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 | 6,457,825 | |
| -1 | -6,457,825 |
Let's try dividing by 4:
6,457,825 ÷ 4 = 1,614,456.25
If the quotient is a whole number, then 4 and 1,614,456.25 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 | 6,457,825 | |
| -1 | 6,457,825 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 23 | 25 | 55 | 115 | 253 | 275 | 575 | 1,021 | 1,265 | 5,105 | 6,325 | 11,231 | 23,483 | 25,525 | 56,155 | 117,415 | 258,313 | 280,775 | 587,075 | 1,291,565 | 6,457,825 |
| -1 | -5 | -11 | -23 | -25 | -55 | -115 | -253 | -275 | -575 | -1,021 | -1,265 | -5,105 | -6,325 | -11,231 | -23,483 | -25,525 | -56,155 | -117,415 | -258,313 | -280,775 | -587,075 | -1,291,565 | -6,457,825 |
