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 104,251,105, 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 | 104,251,105 | |
| -1 | -104,251,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 104,251,105.
Example:
1 x 104,251,105 = 104,251,105
and
-1 x -104,251,105 = 104,251,105
Notice both answers equal 104,251,105
With that explanation out of the way, let's continue. Next, we take the number 104,251,105 and divide it by 2:
104,251,105 ÷ 2 = 52,125,552.5
If the quotient is a whole number, then 2 and 52,125,552.5 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 | 104,251,105 | |
| -1 | -104,251,105 |
Now, we try dividing 104,251,105 by 3:
104,251,105 ÷ 3 = 34,750,368.3333
If the quotient is a whole number, then 3 and 34,750,368.3333 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 | 104,251,105 | |
| -1 | -104,251,105 |
Let's try dividing by 4:
104,251,105 ÷ 4 = 26,062,776.25
If the quotient is a whole number, then 4 and 26,062,776.25 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 | 104,251,105 | |
| -1 | 104,251,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 229 | 1,145 | 1,603 | 8,015 | 13,007 | 65,035 | 91,049 | 455,245 | 2,978,603 | 14,893,015 | 20,850,221 | 104,251,105 |
| -1 | -5 | -7 | -35 | -229 | -1,145 | -1,603 | -8,015 | -13,007 | -65,035 | -91,049 | -455,245 | -2,978,603 | -14,893,015 | -20,850,221 | -104,251,105 |
