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 102,095,905, 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 | 102,095,905 | |
| -1 | -102,095,905 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 102,095,905.
Example:
1 x 102,095,905 = 102,095,905
and
-1 x -102,095,905 = 102,095,905
Notice both answers equal 102,095,905
With that explanation out of the way, let's continue. Next, we take the number 102,095,905 and divide it by 2:
102,095,905 ÷ 2 = 51,047,952.5
If the quotient is a whole number, then 2 and 51,047,952.5 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 | 102,095,905 | |
| -1 | -102,095,905 |
Now, we try dividing 102,095,905 by 3:
102,095,905 ÷ 3 = 34,031,968.3333
If the quotient is a whole number, then 3 and 34,031,968.3333 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 | 102,095,905 | |
| -1 | -102,095,905 |
Let's try dividing by 4:
102,095,905 ÷ 4 = 25,523,976.25
If the quotient is a whole number, then 4 and 25,523,976.25 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 | 102,095,905 | |
| -1 | 102,095,905 |
If you did it right, you will end up with this table:
| 1 | 5 | 89 | 313 | 445 | 733 | 1,565 | 3,665 | 27,857 | 65,237 | 139,285 | 229,429 | 326,185 | 1,147,145 | 20,419,181 | 102,095,905 |
| -1 | -5 | -89 | -313 | -445 | -733 | -1,565 | -3,665 | -27,857 | -65,237 | -139,285 | -229,429 | -326,185 | -1,147,145 | -20,419,181 | -102,095,905 |
