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 25,523,435, 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 | 25,523,435 | |
| -1 | -25,523,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,523,435.
Example:
1 x 25,523,435 = 25,523,435
and
-1 x -25,523,435 = 25,523,435
Notice both answers equal 25,523,435
With that explanation out of the way, let's continue. Next, we take the number 25,523,435 and divide it by 2:
25,523,435 ÷ 2 = 12,761,717.5
If the quotient is a whole number, then 2 and 12,761,717.5 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 | 25,523,435 | |
| -1 | -25,523,435 |
Now, we try dividing 25,523,435 by 3:
25,523,435 ÷ 3 = 8,507,811.6667
If the quotient is a whole number, then 3 and 8,507,811.6667 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 | 25,523,435 | |
| -1 | -25,523,435 |
Let's try dividing by 4:
25,523,435 ÷ 4 = 6,380,858.75
If the quotient is a whole number, then 4 and 6,380,858.75 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 | 25,523,435 | |
| -1 | 25,523,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 71 | 355 | 497 | 2,485 | 10,271 | 51,355 | 71,897 | 359,485 | 729,241 | 3,646,205 | 5,104,687 | 25,523,435 |
| -1 | -5 | -7 | -35 | -71 | -355 | -497 | -2,485 | -10,271 | -51,355 | -71,897 | -359,485 | -729,241 | -3,646,205 | -5,104,687 | -25,523,435 |
