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 25,501,255, 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 | 25,501,255 | |
| -1 | -25,501,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,501,255.
Example:
1 x 25,501,255 = 25,501,255
and
-1 x -25,501,255 = 25,501,255
Notice both answers equal 25,501,255
With that explanation out of the way, let's continue. Next, we take the number 25,501,255 and divide it by 2:
25,501,255 ÷ 2 = 12,750,627.5
If the quotient is a whole number, then 2 and 12,750,627.5 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 | 25,501,255 | |
| -1 | -25,501,255 |
Now, we try dividing 25,501,255 by 3:
25,501,255 ÷ 3 = 8,500,418.3333
If the quotient is a whole number, then 3 and 8,500,418.3333 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 | 25,501,255 | |
| -1 | -25,501,255 |
Let's try dividing by 4:
25,501,255 ÷ 4 = 6,375,313.75
If the quotient is a whole number, then 4 and 6,375,313.75 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 | 25,501,255 | |
| -1 | 25,501,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 103 | 169 | 293 | 515 | 845 | 1,339 | 1,465 | 3,809 | 6,695 | 17,407 | 19,045 | 30,179 | 49,517 | 87,035 | 150,895 | 247,585 | 392,327 | 1,961,635 | 5,100,251 | 25,501,255 |
| -1 | -5 | -13 | -65 | -103 | -169 | -293 | -515 | -845 | -1,339 | -1,465 | -3,809 | -6,695 | -17,407 | -19,045 | -30,179 | -49,517 | -87,035 | -150,895 | -247,585 | -392,327 | -1,961,635 | -5,100,251 | -25,501,255 |
