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 25,101,055, 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 | 25,101,055 | |
| -1 | -25,101,055 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,101,055.
Example:
1 x 25,101,055 = 25,101,055
and
-1 x -25,101,055 = 25,101,055
Notice both answers equal 25,101,055
With that explanation out of the way, let's continue. Next, we take the number 25,101,055 and divide it by 2:
25,101,055 ÷ 2 = 12,550,527.5
If the quotient is a whole number, then 2 and 12,550,527.5 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 | 25,101,055 | |
| -1 | -25,101,055 |
Now, we try dividing 25,101,055 by 3:
25,101,055 ÷ 3 = 8,367,018.3333
If the quotient is a whole number, then 3 and 8,367,018.3333 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 | 25,101,055 | |
| -1 | -25,101,055 |
Let's try dividing by 4:
25,101,055 ÷ 4 = 6,275,263.75
If the quotient is a whole number, then 4 and 6,275,263.75 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 | 25,101,055 | |
| -1 | 25,101,055 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 47 | 235 | 329 | 1,645 | 15,259 | 76,295 | 106,813 | 534,065 | 717,173 | 3,585,865 | 5,020,211 | 25,101,055 |
| -1 | -5 | -7 | -35 | -47 | -235 | -329 | -1,645 | -15,259 | -76,295 | -106,813 | -534,065 | -717,173 | -3,585,865 | -5,020,211 | -25,101,055 |
