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 25,517,569, 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 | 25,517,569 | |
| -1 | -25,517,569 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,517,569.
Example:
1 x 25,517,569 = 25,517,569
and
-1 x -25,517,569 = 25,517,569
Notice both answers equal 25,517,569
With that explanation out of the way, let's continue. Next, we take the number 25,517,569 and divide it by 2:
25,517,569 ÷ 2 = 12,758,784.5
If the quotient is a whole number, then 2 and 12,758,784.5 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 | 25,517,569 | |
| -1 | -25,517,569 |
Now, we try dividing 25,517,569 by 3:
25,517,569 ÷ 3 = 8,505,856.3333
If the quotient is a whole number, then 3 and 8,505,856.3333 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 | 25,517,569 | |
| -1 | -25,517,569 |
Let's try dividing by 4:
25,517,569 ÷ 4 = 6,379,392.25
If the quotient is a whole number, then 4 and 6,379,392.25 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 | 25,517,569 | |
| -1 | 25,517,569 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 47 | 77 | 121 | 329 | 517 | 641 | 847 | 3,619 | 4,487 | 5,687 | 7,051 | 30,127 | 39,809 | 49,357 | 77,561 | 210,889 | 331,397 | 542,927 | 2,319,779 | 3,645,367 | 25,517,569 |
| -1 | -7 | -11 | -47 | -77 | -121 | -329 | -517 | -641 | -847 | -3,619 | -4,487 | -5,687 | -7,051 | -30,127 | -39,809 | -49,357 | -77,561 | -210,889 | -331,397 | -542,927 | -2,319,779 | -3,645,367 | -25,517,569 |
