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 25,601,113, 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 | 25,601,113 | |
| -1 | -25,601,113 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,601,113.
Example:
1 x 25,601,113 = 25,601,113
and
-1 x -25,601,113 = 25,601,113
Notice both answers equal 25,601,113
With that explanation out of the way, let's continue. Next, we take the number 25,601,113 and divide it by 2:
25,601,113 ÷ 2 = 12,800,556.5
If the quotient is a whole number, then 2 and 12,800,556.5 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 | 25,601,113 | |
| -1 | -25,601,113 |
Now, we try dividing 25,601,113 by 3:
25,601,113 ÷ 3 = 8,533,704.3333
If the quotient is a whole number, then 3 and 8,533,704.3333 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 | 25,601,113 | |
| -1 | -25,601,113 |
Let's try dividing by 4:
25,601,113 ÷ 4 = 6,400,278.25
If the quotient is a whole number, then 4 and 6,400,278.25 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 | 25,601,113 | |
| -1 | 25,601,113 |
If you did it right, you will end up with this table:
| 1 | 19 | 29 | 97 | 479 | 551 | 1,843 | 2,813 | 9,101 | 13,891 | 46,463 | 53,447 | 263,929 | 882,797 | 1,347,427 | 25,601,113 |
| -1 | -19 | -29 | -97 | -479 | -551 | -1,843 | -2,813 | -9,101 | -13,891 | -46,463 | -53,447 | -263,929 | -882,797 | -1,347,427 | -25,601,113 |
