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 100,832,831, 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 | 100,832,831 | |
| -1 | -100,832,831 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 100,832,831.
Example:
1 x 100,832,831 = 100,832,831
and
-1 x -100,832,831 = 100,832,831
Notice both answers equal 100,832,831
With that explanation out of the way, let's continue. Next, we take the number 100,832,831 and divide it by 2:
100,832,831 ÷ 2 = 50,416,415.5
If the quotient is a whole number, then 2 and 50,416,415.5 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 | 100,832,831 | |
| -1 | -100,832,831 |
Now, we try dividing 100,832,831 by 3:
100,832,831 ÷ 3 = 33,610,943.6667
If the quotient is a whole number, then 3 and 33,610,943.6667 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 | 100,832,831 | |
| -1 | -100,832,831 |
Let's try dividing by 4:
100,832,831 ÷ 4 = 25,208,207.75
If the quotient is a whole number, then 4 and 25,208,207.75 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 | 100,832,831 | |
| -1 | 100,832,831 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 187 | 523 | 1,031 | 5,753 | 8,891 | 11,341 | 17,527 | 97,801 | 192,797 | 539,213 | 5,931,343 | 9,166,621 | 100,832,831 |
| -1 | -11 | -17 | -187 | -523 | -1,031 | -5,753 | -8,891 | -11,341 | -17,527 | -97,801 | -192,797 | -539,213 | -5,931,343 | -9,166,621 | -100,832,831 |
