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 7,901,725, 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 | 7,901,725 | |
| -1 | -7,901,725 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,901,725.
Example:
1 x 7,901,725 = 7,901,725
and
-1 x -7,901,725 = 7,901,725
Notice both answers equal 7,901,725
With that explanation out of the way, let's continue. Next, we take the number 7,901,725 and divide it by 2:
7,901,725 ÷ 2 = 3,950,862.5
If the quotient is a whole number, then 2 and 3,950,862.5 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 | 7,901,725 | |
| -1 | -7,901,725 |
Now, we try dividing 7,901,725 by 3:
7,901,725 ÷ 3 = 2,633,908.3333
If the quotient is a whole number, then 3 and 2,633,908.3333 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 | 7,901,725 | |
| -1 | -7,901,725 |
Let's try dividing by 4:
7,901,725 ÷ 4 = 1,975,431.25
If the quotient is a whole number, then 4 and 1,975,431.25 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 | 7,901,725 | |
| -1 | 7,901,725 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 41 | 65 | 205 | 325 | 533 | 593 | 1,025 | 2,665 | 2,965 | 7,709 | 13,325 | 14,825 | 24,313 | 38,545 | 121,565 | 192,725 | 316,069 | 607,825 | 1,580,345 | 7,901,725 |
| -1 | -5 | -13 | -25 | -41 | -65 | -205 | -325 | -533 | -593 | -1,025 | -2,665 | -2,965 | -7,709 | -13,325 | -14,825 | -24,313 | -38,545 | -121,565 | -192,725 | -316,069 | -607,825 | -1,580,345 | -7,901,725 |
