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 25,273,127, 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 | 25,273,127 | |
| -1 | -25,273,127 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,273,127.
Example:
1 x 25,273,127 = 25,273,127
and
-1 x -25,273,127 = 25,273,127
Notice both answers equal 25,273,127
With that explanation out of the way, let's continue. Next, we take the number 25,273,127 and divide it by 2:
25,273,127 ÷ 2 = 12,636,563.5
If the quotient is a whole number, then 2 and 12,636,563.5 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 | 25,273,127 | |
| -1 | -25,273,127 |
Now, we try dividing 25,273,127 by 3:
25,273,127 ÷ 3 = 8,424,375.6667
If the quotient is a whole number, then 3 and 8,424,375.6667 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 | 25,273,127 | |
| -1 | -25,273,127 |
Let's try dividing by 4:
25,273,127 ÷ 4 = 6,318,281.75
If the quotient is a whole number, then 4 and 6,318,281.75 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 | 25,273,127 | |
| -1 | 25,273,127 |
If you did it right, you will end up with this table:
| 1 | 11 | 79 | 127 | 229 | 869 | 1,397 | 2,519 | 10,033 | 18,091 | 29,083 | 110,363 | 199,001 | 319,913 | 2,297,557 | 25,273,127 |
| -1 | -11 | -79 | -127 | -229 | -869 | -1,397 | -2,519 | -10,033 | -18,091 | -29,083 | -110,363 | -199,001 | -319,913 | -2,297,557 | -25,273,127 |
