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 25,455,353, 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 | 25,455,353 | |
| -1 | -25,455,353 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,455,353.
Example:
1 x 25,455,353 = 25,455,353
and
-1 x -25,455,353 = 25,455,353
Notice both answers equal 25,455,353
With that explanation out of the way, let's continue. Next, we take the number 25,455,353 and divide it by 2:
25,455,353 ÷ 2 = 12,727,676.5
If the quotient is a whole number, then 2 and 12,727,676.5 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 | 25,455,353 | |
| -1 | -25,455,353 |
Now, we try dividing 25,455,353 by 3:
25,455,353 ÷ 3 = 8,485,117.6667
If the quotient is a whole number, then 3 and 8,485,117.6667 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 | 25,455,353 | |
| -1 | -25,455,353 |
Let's try dividing by 4:
25,455,353 ÷ 4 = 6,363,838.25
If the quotient is a whole number, then 4 and 6,363,838.25 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 | 25,455,353 | |
| -1 | 25,455,353 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 49 | 77 | 83 | 539 | 569 | 581 | 913 | 3,983 | 4,067 | 6,259 | 6,391 | 27,881 | 43,813 | 44,737 | 47,227 | 306,691 | 330,589 | 519,497 | 2,314,123 | 3,636,479 | 25,455,353 |
| -1 | -7 | -11 | -49 | -77 | -83 | -539 | -569 | -581 | -913 | -3,983 | -4,067 | -6,259 | -6,391 | -27,881 | -43,813 | -44,737 | -47,227 | -306,691 | -330,589 | -519,497 | -2,314,123 | -3,636,479 | -25,455,353 |
