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 25,534,369, 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 | 25,534,369 | |
| -1 | -25,534,369 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,534,369.
Example:
1 x 25,534,369 = 25,534,369
and
-1 x -25,534,369 = 25,534,369
Notice both answers equal 25,534,369
With that explanation out of the way, let's continue. Next, we take the number 25,534,369 and divide it by 2:
25,534,369 ÷ 2 = 12,767,184.5
If the quotient is a whole number, then 2 and 12,767,184.5 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 | 25,534,369 | |
| -1 | -25,534,369 |
Now, we try dividing 25,534,369 by 3:
25,534,369 ÷ 3 = 8,511,456.3333
If the quotient is a whole number, then 3 and 8,511,456.3333 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 | 25,534,369 | |
| -1 | -25,534,369 |
Let's try dividing by 4:
25,534,369 ÷ 4 = 6,383,592.25
If the quotient is a whole number, then 4 and 6,383,592.25 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 | 25,534,369 | |
| -1 | 25,534,369 |
If you did it right, you will end up with this table:
| 1 | 7 | 71 | 83 | 497 | 581 | 619 | 4,333 | 5,893 | 41,251 | 43,949 | 51,377 | 307,643 | 359,639 | 3,647,767 | 25,534,369 |
| -1 | -7 | -71 | -83 | -497 | -581 | -619 | -4,333 | -5,893 | -41,251 | -43,949 | -51,377 | -307,643 | -359,639 | -3,647,767 | -25,534,369 |
