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 102,320,195, 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 | 102,320,195 | |
| -1 | -102,320,195 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 102,320,195.
Example:
1 x 102,320,195 = 102,320,195
and
-1 x -102,320,195 = 102,320,195
Notice both answers equal 102,320,195
With that explanation out of the way, let's continue. Next, we take the number 102,320,195 and divide it by 2:
102,320,195 ÷ 2 = 51,160,097.5
If the quotient is a whole number, then 2 and 51,160,097.5 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 | 102,320,195 | |
| -1 | -102,320,195 |
Now, we try dividing 102,320,195 by 3:
102,320,195 ÷ 3 = 34,106,731.6667
If the quotient is a whole number, then 3 and 34,106,731.6667 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 | 102,320,195 | |
| -1 | -102,320,195 |
Let's try dividing by 4:
102,320,195 ÷ 4 = 25,580,048.75
If the quotient is a whole number, then 4 and 25,580,048.75 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 | 102,320,195 | |
| -1 | 102,320,195 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 617 | 1,951 | 3,085 | 9,755 | 10,489 | 33,167 | 52,445 | 165,835 | 1,203,767 | 6,018,835 | 20,464,039 | 102,320,195 |
| -1 | -5 | -17 | -85 | -617 | -1,951 | -3,085 | -9,755 | -10,489 | -33,167 | -52,445 | -165,835 | -1,203,767 | -6,018,835 | -20,464,039 | -102,320,195 |
