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 10,597,885, 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 | 10,597,885 | |
| -1 | -10,597,885 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,597,885.
Example:
1 x 10,597,885 = 10,597,885
and
-1 x -10,597,885 = 10,597,885
Notice both answers equal 10,597,885
With that explanation out of the way, let's continue. Next, we take the number 10,597,885 and divide it by 2:
10,597,885 ÷ 2 = 5,298,942.5
If the quotient is a whole number, then 2 and 5,298,942.5 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 | 10,597,885 | |
| -1 | -10,597,885 |
Now, we try dividing 10,597,885 by 3:
10,597,885 ÷ 3 = 3,532,628.3333
If the quotient is a whole number, then 3 and 3,532,628.3333 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 | 10,597,885 | |
| -1 | -10,597,885 |
Let's try dividing by 4:
10,597,885 ÷ 4 = 2,649,471.25
If the quotient is a whole number, then 4 and 2,649,471.25 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 | 10,597,885 | |
| -1 | 10,597,885 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 41 | 85 | 205 | 697 | 3,041 | 3,485 | 15,205 | 51,697 | 124,681 | 258,485 | 623,405 | 2,119,577 | 10,597,885 |
| -1 | -5 | -17 | -41 | -85 | -205 | -697 | -3,041 | -3,485 | -15,205 | -51,697 | -124,681 | -258,485 | -623,405 | -2,119,577 | -10,597,885 |
