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 102,612,065, 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 | 102,612,065 | |
| -1 | -102,612,065 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 102,612,065.
Example:
1 x 102,612,065 = 102,612,065
and
-1 x -102,612,065 = 102,612,065
Notice both answers equal 102,612,065
With that explanation out of the way, let's continue. Next, we take the number 102,612,065 and divide it by 2:
102,612,065 ÷ 2 = 51,306,032.5
If the quotient is a whole number, then 2 and 51,306,032.5 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 | 102,612,065 | |
| -1 | -102,612,065 |
Now, we try dividing 102,612,065 by 3:
102,612,065 ÷ 3 = 34,204,021.6667
If the quotient is a whole number, then 3 and 34,204,021.6667 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 | 102,612,065 | |
| -1 | -102,612,065 |
Let's try dividing by 4:
102,612,065 ÷ 4 = 25,653,016.25
If the quotient is a whole number, then 4 and 25,653,016.25 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 | 102,612,065 | |
| -1 | 102,612,065 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 61 | 95 | 305 | 1,159 | 5,795 | 17,707 | 88,535 | 336,433 | 1,080,127 | 1,682,165 | 5,400,635 | 20,522,413 | 102,612,065 |
| -1 | -5 | -19 | -61 | -95 | -305 | -1,159 | -5,795 | -17,707 | -88,535 | -336,433 | -1,080,127 | -1,682,165 | -5,400,635 | -20,522,413 | -102,612,065 |
