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 104,120,195, 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 | 104,120,195 | |
| -1 | -104,120,195 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 104,120,195.
Example:
1 x 104,120,195 = 104,120,195
and
-1 x -104,120,195 = 104,120,195
Notice both answers equal 104,120,195
With that explanation out of the way, let's continue. Next, we take the number 104,120,195 and divide it by 2:
104,120,195 ÷ 2 = 52,060,097.5
If the quotient is a whole number, then 2 and 52,060,097.5 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 | 104,120,195 | |
| -1 | -104,120,195 |
Now, we try dividing 104,120,195 by 3:
104,120,195 ÷ 3 = 34,706,731.6667
If the quotient is a whole number, then 3 and 34,706,731.6667 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 | 104,120,195 | |
| -1 | -104,120,195 |
Let's try dividing by 4:
104,120,195 ÷ 4 = 26,030,048.75
If the quotient is a whole number, then 4 and 26,030,048.75 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 | 104,120,195 | |
| -1 | 104,120,195 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 709 | 1,277 | 3,545 | 6,385 | 16,307 | 29,371 | 81,535 | 146,855 | 905,393 | 4,526,965 | 20,824,039 | 104,120,195 |
| -1 | -5 | -23 | -115 | -709 | -1,277 | -3,545 | -6,385 | -16,307 | -29,371 | -81,535 | -146,855 | -905,393 | -4,526,965 | -20,824,039 | -104,120,195 |
