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 102,032,215, 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 | 102,032,215 | |
| -1 | -102,032,215 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 102,032,215.
Example:
1 x 102,032,215 = 102,032,215
and
-1 x -102,032,215 = 102,032,215
Notice both answers equal 102,032,215
With that explanation out of the way, let's continue. Next, we take the number 102,032,215 and divide it by 2:
102,032,215 ÷ 2 = 51,016,107.5
If the quotient is a whole number, then 2 and 51,016,107.5 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 | 102,032,215 | |
| -1 | -102,032,215 |
Now, we try dividing 102,032,215 by 3:
102,032,215 ÷ 3 = 34,010,738.3333
If the quotient is a whole number, then 3 and 34,010,738.3333 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 | 102,032,215 | |
| -1 | -102,032,215 |
Let's try dividing by 4:
102,032,215 ÷ 4 = 25,508,053.75
If the quotient is a whole number, then 4 and 25,508,053.75 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 | 102,032,215 | |
| -1 | 102,032,215 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 211 | 1,055 | 3,587 | 5,689 | 17,935 | 28,445 | 96,713 | 483,565 | 1,200,379 | 6,001,895 | 20,406,443 | 102,032,215 |
| -1 | -5 | -17 | -85 | -211 | -1,055 | -3,587 | -5,689 | -17,935 | -28,445 | -96,713 | -483,565 | -1,200,379 | -6,001,895 | -20,406,443 | -102,032,215 |
