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 102,214,855, 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 | 102,214,855 | |
| -1 | -102,214,855 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 102,214,855.
Example:
1 x 102,214,855 = 102,214,855
and
-1 x -102,214,855 = 102,214,855
Notice both answers equal 102,214,855
With that explanation out of the way, let's continue. Next, we take the number 102,214,855 and divide it by 2:
102,214,855 ÷ 2 = 51,107,427.5
If the quotient is a whole number, then 2 and 51,107,427.5 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 | 102,214,855 | |
| -1 | -102,214,855 |
Now, we try dividing 102,214,855 by 3:
102,214,855 ÷ 3 = 34,071,618.3333
If the quotient is a whole number, then 3 and 34,071,618.3333 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 | 102,214,855 | |
| -1 | -102,214,855 |
Let's try dividing by 4:
102,214,855 ÷ 4 = 25,553,713.75
If the quotient is a whole number, then 4 and 25,553,713.75 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 | 102,214,855 | |
| -1 | 102,214,855 |
If you did it right, you will end up with this table:
| 1 | 5 | 163 | 167 | 751 | 815 | 835 | 3,755 | 27,221 | 122,413 | 125,417 | 136,105 | 612,065 | 627,085 | 20,442,971 | 102,214,855 |
| -1 | -5 | -163 | -167 | -751 | -815 | -835 | -3,755 | -27,221 | -122,413 | -125,417 | -136,105 | -612,065 | -627,085 | -20,442,971 | -102,214,855 |
