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 102,025,517, 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 | 102,025,517 | |
| -1 | -102,025,517 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 102,025,517.
Example:
1 x 102,025,517 = 102,025,517
and
-1 x -102,025,517 = 102,025,517
Notice both answers equal 102,025,517
With that explanation out of the way, let's continue. Next, we take the number 102,025,517 and divide it by 2:
102,025,517 ÷ 2 = 51,012,758.5
If the quotient is a whole number, then 2 and 51,012,758.5 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 | 102,025,517 | |
| -1 | -102,025,517 |
Now, we try dividing 102,025,517 by 3:
102,025,517 ÷ 3 = 34,008,505.6667
If the quotient is a whole number, then 3 and 34,008,505.6667 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 | 102,025,517 | |
| -1 | -102,025,517 |
Let's try dividing by 4:
102,025,517 ÷ 4 = 25,506,379.25
If the quotient is a whole number, then 4 and 25,506,379.25 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 | 102,025,517 | |
| -1 | 102,025,517 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 103 | 187 | 1,133 | 1,751 | 5,297 | 19,261 | 58,267 | 90,049 | 545,591 | 990,539 | 6,001,501 | 9,275,047 | 102,025,517 |
| -1 | -11 | -17 | -103 | -187 | -1,133 | -1,751 | -5,297 | -19,261 | -58,267 | -90,049 | -545,591 | -990,539 | -6,001,501 | -9,275,047 | -102,025,517 |
