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 25,400,027, 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 | 25,400,027 | |
| -1 | -25,400,027 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,400,027.
Example:
1 x 25,400,027 = 25,400,027
and
-1 x -25,400,027 = 25,400,027
Notice both answers equal 25,400,027
With that explanation out of the way, let's continue. Next, we take the number 25,400,027 and divide it by 2:
25,400,027 ÷ 2 = 12,700,013.5
If the quotient is a whole number, then 2 and 12,700,013.5 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 | 25,400,027 | |
| -1 | -25,400,027 |
Now, we try dividing 25,400,027 by 3:
25,400,027 ÷ 3 = 8,466,675.6667
If the quotient is a whole number, then 3 and 8,466,675.6667 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 | 25,400,027 | |
| -1 | -25,400,027 |
Let's try dividing by 4:
25,400,027 ÷ 4 = 6,350,006.75
If the quotient is a whole number, then 4 and 6,350,006.75 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 | 25,400,027 | |
| -1 | 25,400,027 |
If you did it right, you will end up with this table:
| 1 | 23 | 29 | 113 | 337 | 667 | 2,599 | 3,277 | 7,751 | 9,773 | 38,081 | 75,371 | 224,779 | 875,863 | 1,104,349 | 25,400,027 |
| -1 | -23 | -29 | -113 | -337 | -667 | -2,599 | -3,277 | -7,751 | -9,773 | -38,081 | -75,371 | -224,779 | -875,863 | -1,104,349 | -25,400,027 |
