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 100,313,125, 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 | 100,313,125 | |
| -1 | -100,313,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 100,313,125.
Example:
1 x 100,313,125 = 100,313,125
and
-1 x -100,313,125 = 100,313,125
Notice both answers equal 100,313,125
With that explanation out of the way, let's continue. Next, we take the number 100,313,125 and divide it by 2:
100,313,125 ÷ 2 = 50,156,562.5
If the quotient is a whole number, then 2 and 50,156,562.5 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 | 100,313,125 | |
| -1 | -100,313,125 |
Now, we try dividing 100,313,125 by 3:
100,313,125 ÷ 3 = 33,437,708.3333
If the quotient is a whole number, then 3 and 33,437,708.3333 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 | 100,313,125 | |
| -1 | -100,313,125 |
Let's try dividing by 4:
100,313,125 ÷ 4 = 25,078,281.25
If the quotient is a whole number, then 4 and 25,078,281.25 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 | 100,313,125 | |
| -1 | 100,313,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 125 | 275 | 625 | 1,375 | 6,875 | 14,591 | 72,955 | 160,501 | 364,775 | 802,505 | 1,823,875 | 4,012,525 | 9,119,375 | 20,062,625 | 100,313,125 |
| -1 | -5 | -11 | -25 | -55 | -125 | -275 | -625 | -1,375 | -6,875 | -14,591 | -72,955 | -160,501 | -364,775 | -802,505 | -1,823,875 | -4,012,525 | -9,119,375 | -20,062,625 | -100,313,125 |
