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 25,610,425, 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 | 25,610,425 | |
| -1 | -25,610,425 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,610,425.
Example:
1 x 25,610,425 = 25,610,425
and
-1 x -25,610,425 = 25,610,425
Notice both answers equal 25,610,425
With that explanation out of the way, let's continue. Next, we take the number 25,610,425 and divide it by 2:
25,610,425 ÷ 2 = 12,805,212.5
If the quotient is a whole number, then 2 and 12,805,212.5 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 | 25,610,425 | |
| -1 | -25,610,425 |
Now, we try dividing 25,610,425 by 3:
25,610,425 ÷ 3 = 8,536,808.3333
If the quotient is a whole number, then 3 and 8,536,808.3333 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 | 25,610,425 | |
| -1 | -25,610,425 |
Let's try dividing by 4:
25,610,425 ÷ 4 = 6,402,606.25
If the quotient is a whole number, then 4 and 6,402,606.25 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 | 25,610,425 | |
| -1 | 25,610,425 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 59 | 97 | 179 | 295 | 485 | 895 | 1,475 | 2,425 | 4,475 | 5,723 | 10,561 | 17,363 | 28,615 | 52,805 | 86,815 | 143,075 | 264,025 | 434,075 | 1,024,417 | 5,122,085 | 25,610,425 |
| -1 | -5 | -25 | -59 | -97 | -179 | -295 | -485 | -895 | -1,475 | -2,425 | -4,475 | -5,723 | -10,561 | -17,363 | -28,615 | -52,805 | -86,815 | -143,075 | -264,025 | -434,075 | -1,024,417 | -5,122,085 | -25,610,425 |
