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 7,887,425, 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 | 7,887,425 | |
| -1 | -7,887,425 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,887,425.
Example:
1 x 7,887,425 = 7,887,425
and
-1 x -7,887,425 = 7,887,425
Notice both answers equal 7,887,425
With that explanation out of the way, let's continue. Next, we take the number 7,887,425 and divide it by 2:
7,887,425 ÷ 2 = 3,943,712.5
If the quotient is a whole number, then 2 and 3,943,712.5 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 | 7,887,425 | |
| -1 | -7,887,425 |
Now, we try dividing 7,887,425 by 3:
7,887,425 ÷ 3 = 2,629,141.6667
If the quotient is a whole number, then 3 and 2,629,141.6667 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 | 7,887,425 | |
| -1 | -7,887,425 |
Let's try dividing by 4:
7,887,425 ÷ 4 = 1,971,856.25
If the quotient is a whole number, then 4 and 1,971,856.25 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 | 7,887,425 | |
| -1 | 7,887,425 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 25 | 35 | 65 | 91 | 175 | 325 | 455 | 2,275 | 3,467 | 17,335 | 24,269 | 45,071 | 86,675 | 121,345 | 225,355 | 315,497 | 606,725 | 1,126,775 | 1,577,485 | 7,887,425 |
| -1 | -5 | -7 | -13 | -25 | -35 | -65 | -91 | -175 | -325 | -455 | -2,275 | -3,467 | -17,335 | -24,269 | -45,071 | -86,675 | -121,345 | -225,355 | -315,497 | -606,725 | -1,126,775 | -1,577,485 | -7,887,425 |
