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 845,635,259, 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 | 845,635,259 | |
| -1 | -845,635,259 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 845,635,259.
Example:
1 x 845,635,259 = 845,635,259
and
-1 x -845,635,259 = 845,635,259
Notice both answers equal 845,635,259
With that explanation out of the way, let's continue. Next, we take the number 845,635,259 and divide it by 2:
845,635,259 ÷ 2 = 422,817,629.5
If the quotient is a whole number, then 2 and 422,817,629.5 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 | 845,635,259 | |
| -1 | -845,635,259 |
Now, we try dividing 845,635,259 by 3:
845,635,259 ÷ 3 = 281,878,419.6667
If the quotient is a whole number, then 3 and 281,878,419.6667 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 | 845,635,259 | |
| -1 | -845,635,259 |
Let's try dividing by 4:
845,635,259 ÷ 4 = 211,408,814.75
If the quotient is a whole number, then 4 and 211,408,814.75 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 | 845,635,259 | |
| -1 | 845,635,259 |
If you did it right, you will end up with this table:
| 1 | 7 | 37 | 59 | 259 | 413 | 2,183 | 15,281 | 55,339 | 387,373 | 2,047,543 | 3,265,001 | 14,332,801 | 22,855,007 | 120,805,037 | 845,635,259 |
| -1 | -7 | -37 | -59 | -259 | -413 | -2,183 | -15,281 | -55,339 | -387,373 | -2,047,543 | -3,265,001 | -14,332,801 | -22,855,007 | -120,805,037 | -845,635,259 |
