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 25,925,977, 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 | 25,925,977 | |
| -1 | -25,925,977 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,925,977.
Example:
1 x 25,925,977 = 25,925,977
and
-1 x -25,925,977 = 25,925,977
Notice both answers equal 25,925,977
With that explanation out of the way, let's continue. Next, we take the number 25,925,977 and divide it by 2:
25,925,977 ÷ 2 = 12,962,988.5
If the quotient is a whole number, then 2 and 12,962,988.5 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 | 25,925,977 | |
| -1 | -25,925,977 |
Now, we try dividing 25,925,977 by 3:
25,925,977 ÷ 3 = 8,641,992.3333
If the quotient is a whole number, then 3 and 8,641,992.3333 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 | 25,925,977 | |
| -1 | -25,925,977 |
Let's try dividing by 4:
25,925,977 ÷ 4 = 6,481,494.25
If the quotient is a whole number, then 4 and 6,481,494.25 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 | 25,925,977 | |
| -1 | 25,925,977 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 109 | 763 | 1,199 | 3,089 | 8,393 | 21,623 | 33,979 | 237,853 | 336,701 | 2,356,907 | 3,703,711 | 25,925,977 |
| -1 | -7 | -11 | -77 | -109 | -763 | -1,199 | -3,089 | -8,393 | -21,623 | -33,979 | -237,853 | -336,701 | -2,356,907 | -3,703,711 | -25,925,977 |
