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 25,111,075, 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 | 25,111,075 | |
| -1 | -25,111,075 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,111,075.
Example:
1 x 25,111,075 = 25,111,075
and
-1 x -25,111,075 = 25,111,075
Notice both answers equal 25,111,075
With that explanation out of the way, let's continue. Next, we take the number 25,111,075 and divide it by 2:
25,111,075 ÷ 2 = 12,555,537.5
If the quotient is a whole number, then 2 and 12,555,537.5 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 | 25,111,075 | |
| -1 | -25,111,075 |
Now, we try dividing 25,111,075 by 3:
25,111,075 ÷ 3 = 8,370,358.3333
If the quotient is a whole number, then 3 and 8,370,358.3333 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 | 25,111,075 | |
| -1 | -25,111,075 |
Let's try dividing by 4:
25,111,075 ÷ 4 = 6,277,768.75
If the quotient is a whole number, then 4 and 6,277,768.75 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 | 25,111,075 | |
| -1 | 25,111,075 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 127 | 275 | 635 | 719 | 1,397 | 3,175 | 3,595 | 6,985 | 7,909 | 17,975 | 34,925 | 39,545 | 91,313 | 197,725 | 456,565 | 1,004,443 | 2,282,825 | 5,022,215 | 25,111,075 |
| -1 | -5 | -11 | -25 | -55 | -127 | -275 | -635 | -719 | -1,397 | -3,175 | -3,595 | -6,985 | -7,909 | -17,975 | -34,925 | -39,545 | -91,313 | -197,725 | -456,565 | -1,004,443 | -2,282,825 | -5,022,215 | -25,111,075 |
