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 100,588,873, 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 | 100,588,873 | |
| -1 | -100,588,873 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 100,588,873.
Example:
1 x 100,588,873 = 100,588,873
and
-1 x -100,588,873 = 100,588,873
Notice both answers equal 100,588,873
With that explanation out of the way, let's continue. Next, we take the number 100,588,873 and divide it by 2:
100,588,873 ÷ 2 = 50,294,436.5
If the quotient is a whole number, then 2 and 50,294,436.5 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 | 100,588,873 | |
| -1 | -100,588,873 |
Now, we try dividing 100,588,873 by 3:
100,588,873 ÷ 3 = 33,529,624.3333
If the quotient is a whole number, then 3 and 33,529,624.3333 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 | 100,588,873 | |
| -1 | -100,588,873 |
Let's try dividing by 4:
100,588,873 ÷ 4 = 25,147,218.25
If the quotient is a whole number, then 4 and 25,147,218.25 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 | 100,588,873 | |
| -1 | 100,588,873 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 103 | 121 | 721 | 847 | 1,133 | 1,153 | 7,931 | 8,071 | 12,463 | 12,683 | 87,241 | 88,781 | 118,759 | 139,513 | 831,313 | 976,591 | 1,306,349 | 9,144,443 | 14,369,839 | 100,588,873 |
| -1 | -7 | -11 | -77 | -103 | -121 | -721 | -847 | -1,133 | -1,153 | -7,931 | -8,071 | -12,463 | -12,683 | -87,241 | -88,781 | -118,759 | -139,513 | -831,313 | -976,591 | -1,306,349 | -9,144,443 | -14,369,839 | -100,588,873 |
