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 25,598,035, 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 | 25,598,035 | |
| -1 | -25,598,035 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,598,035.
Example:
1 x 25,598,035 = 25,598,035
and
-1 x -25,598,035 = 25,598,035
Notice both answers equal 25,598,035
With that explanation out of the way, let's continue. Next, we take the number 25,598,035 and divide it by 2:
25,598,035 ÷ 2 = 12,799,017.5
If the quotient is a whole number, then 2 and 12,799,017.5 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 | 25,598,035 | |
| -1 | -25,598,035 |
Now, we try dividing 25,598,035 by 3:
25,598,035 ÷ 3 = 8,532,678.3333
If the quotient is a whole number, then 3 and 8,532,678.3333 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 | 25,598,035 | |
| -1 | -25,598,035 |
Let's try dividing by 4:
25,598,035 ÷ 4 = 6,399,508.75
If the quotient is a whole number, then 4 and 6,399,508.75 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 | 25,598,035 | |
| -1 | 25,598,035 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 59 | 95 | 295 | 1,121 | 4,567 | 5,605 | 22,835 | 86,773 | 269,453 | 433,865 | 1,347,265 | 5,119,607 | 25,598,035 |
| -1 | -5 | -19 | -59 | -95 | -295 | -1,121 | -4,567 | -5,605 | -22,835 | -86,773 | -269,453 | -433,865 | -1,347,265 | -5,119,607 | -25,598,035 |
