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 25,916,075, 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 | 25,916,075 | |
| -1 | -25,916,075 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,916,075.
Example:
1 x 25,916,075 = 25,916,075
and
-1 x -25,916,075 = 25,916,075
Notice both answers equal 25,916,075
With that explanation out of the way, let's continue. Next, we take the number 25,916,075 and divide it by 2:
25,916,075 ÷ 2 = 12,958,037.5
If the quotient is a whole number, then 2 and 12,958,037.5 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 | 25,916,075 | |
| -1 | -25,916,075 |
Now, we try dividing 25,916,075 by 3:
25,916,075 ÷ 3 = 8,638,691.6667
If the quotient is a whole number, then 3 and 8,638,691.6667 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 | 25,916,075 | |
| -1 | -25,916,075 |
Let's try dividing by 4:
25,916,075 ÷ 4 = 6,479,018.75
If the quotient is a whole number, then 4 and 6,479,018.75 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 | 25,916,075 | |
| -1 | 25,916,075 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 85 | 211 | 289 | 425 | 1,055 | 1,445 | 3,587 | 4,913 | 5,275 | 7,225 | 17,935 | 24,565 | 60,979 | 89,675 | 122,825 | 304,895 | 1,036,643 | 1,524,475 | 5,183,215 | 25,916,075 |
| -1 | -5 | -17 | -25 | -85 | -211 | -289 | -425 | -1,055 | -1,445 | -3,587 | -4,913 | -5,275 | -7,225 | -17,935 | -24,565 | -60,979 | -89,675 | -122,825 | -304,895 | -1,036,643 | -1,524,475 | -5,183,215 | -25,916,075 |
