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 100,604,585, 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 | 100,604,585 | |
| -1 | -100,604,585 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 100,604,585.
Example:
1 x 100,604,585 = 100,604,585
and
-1 x -100,604,585 = 100,604,585
Notice both answers equal 100,604,585
With that explanation out of the way, let's continue. Next, we take the number 100,604,585 and divide it by 2:
100,604,585 ÷ 2 = 50,302,292.5
If the quotient is a whole number, then 2 and 50,302,292.5 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 | 100,604,585 | |
| -1 | -100,604,585 |
Now, we try dividing 100,604,585 by 3:
100,604,585 ÷ 3 = 33,534,861.6667
If the quotient is a whole number, then 3 and 33,534,861.6667 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 | 100,604,585 | |
| -1 | -100,604,585 |
Let's try dividing by 4:
100,604,585 ÷ 4 = 25,151,146.25
If the quotient is a whole number, then 4 and 25,151,146.25 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 | 100,604,585 | |
| -1 | 100,604,585 |
If you did it right, you will end up with this table:
| 1 | 5 | 73 | 101 | 365 | 505 | 2,729 | 7,373 | 13,645 | 36,865 | 199,217 | 275,629 | 996,085 | 1,378,145 | 20,120,917 | 100,604,585 |
| -1 | -5 | -73 | -101 | -365 | -505 | -2,729 | -7,373 | -13,645 | -36,865 | -199,217 | -275,629 | -996,085 | -1,378,145 | -20,120,917 | -100,604,585 |
