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 6,663,425, 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 | 6,663,425 | |
| -1 | -6,663,425 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 6,663,425.
Example:
1 x 6,663,425 = 6,663,425
and
-1 x -6,663,425 = 6,663,425
Notice both answers equal 6,663,425
With that explanation out of the way, let's continue. Next, we take the number 6,663,425 and divide it by 2:
6,663,425 ÷ 2 = 3,331,712.5
If the quotient is a whole number, then 2 and 3,331,712.5 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 | 6,663,425 | |
| -1 | -6,663,425 |
Now, we try dividing 6,663,425 by 3:
6,663,425 ÷ 3 = 2,221,141.6667
If the quotient is a whole number, then 3 and 2,221,141.6667 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 | 6,663,425 | |
| -1 | -6,663,425 |
Let's try dividing by 4:
6,663,425 ÷ 4 = 1,665,856.25
If the quotient is a whole number, then 4 and 1,665,856.25 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 | 6,663,425 | |
| -1 | 6,663,425 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 47 | 53 | 107 | 235 | 265 | 535 | 1,175 | 1,325 | 2,491 | 2,675 | 5,029 | 5,671 | 12,455 | 25,145 | 28,355 | 62,275 | 125,725 | 141,775 | 266,537 | 1,332,685 | 6,663,425 |
| -1 | -5 | -25 | -47 | -53 | -107 | -235 | -265 | -535 | -1,175 | -1,325 | -2,491 | -2,675 | -5,029 | -5,671 | -12,455 | -25,145 | -28,355 | -62,275 | -125,725 | -141,775 | -266,537 | -1,332,685 | -6,663,425 |
