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 25,006,795, 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 | 25,006,795 | |
| -1 | -25,006,795 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,006,795.
Example:
1 x 25,006,795 = 25,006,795
and
-1 x -25,006,795 = 25,006,795
Notice both answers equal 25,006,795
With that explanation out of the way, let's continue. Next, we take the number 25,006,795 and divide it by 2:
25,006,795 ÷ 2 = 12,503,397.5
If the quotient is a whole number, then 2 and 12,503,397.5 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 | 25,006,795 | |
| -1 | -25,006,795 |
Now, we try dividing 25,006,795 by 3:
25,006,795 ÷ 3 = 8,335,598.3333
If the quotient is a whole number, then 3 and 8,335,598.3333 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 | 25,006,795 | |
| -1 | -25,006,795 |
Let's try dividing by 4:
25,006,795 ÷ 4 = 6,251,698.75
If the quotient is a whole number, then 4 and 6,251,698.75 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 | 25,006,795 | |
| -1 | 25,006,795 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 139 | 695 | 1,529 | 3,271 | 7,645 | 16,355 | 35,981 | 179,905 | 454,669 | 2,273,345 | 5,001,359 | 25,006,795 |
| -1 | -5 | -11 | -55 | -139 | -695 | -1,529 | -3,271 | -7,645 | -16,355 | -35,981 | -179,905 | -454,669 | -2,273,345 | -5,001,359 | -25,006,795 |
