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 25,355,309, 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 | 25,355,309 | |
| -1 | -25,355,309 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,355,309.
Example:
1 x 25,355,309 = 25,355,309
and
-1 x -25,355,309 = 25,355,309
Notice both answers equal 25,355,309
With that explanation out of the way, let's continue. Next, we take the number 25,355,309 and divide it by 2:
25,355,309 ÷ 2 = 12,677,654.5
If the quotient is a whole number, then 2 and 12,677,654.5 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 | 25,355,309 | |
| -1 | -25,355,309 |
Now, we try dividing 25,355,309 by 3:
25,355,309 ÷ 3 = 8,451,769.6667
If the quotient is a whole number, then 3 and 8,451,769.6667 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 | 25,355,309 | |
| -1 | -25,355,309 |
Let's try dividing by 4:
25,355,309 ÷ 4 = 6,338,827.25
If the quotient is a whole number, then 4 and 6,338,827.25 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 | 25,355,309 | |
| -1 | 25,355,309 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 59 | 73 | 203 | 413 | 511 | 841 | 1,711 | 2,117 | 4,307 | 5,887 | 11,977 | 14,819 | 30,149 | 49,619 | 61,393 | 124,903 | 347,333 | 429,751 | 874,321 | 3,622,187 | 25,355,309 |
| -1 | -7 | -29 | -59 | -73 | -203 | -413 | -511 | -841 | -1,711 | -2,117 | -4,307 | -5,887 | -11,977 | -14,819 | -30,149 | -49,619 | -61,393 | -124,903 | -347,333 | -429,751 | -874,321 | -3,622,187 | -25,355,309 |
