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 102,406,315, 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 | 102,406,315 | |
| -1 | -102,406,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 102,406,315.
Example:
1 x 102,406,315 = 102,406,315
and
-1 x -102,406,315 = 102,406,315
Notice both answers equal 102,406,315
With that explanation out of the way, let's continue. Next, we take the number 102,406,315 and divide it by 2:
102,406,315 ÷ 2 = 51,203,157.5
If the quotient is a whole number, then 2 and 51,203,157.5 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 | 102,406,315 | |
| -1 | -102,406,315 |
Now, we try dividing 102,406,315 by 3:
102,406,315 ÷ 3 = 34,135,438.3333
If the quotient is a whole number, then 3 and 34,135,438.3333 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 | 102,406,315 | |
| -1 | -102,406,315 |
Let's try dividing by 4:
102,406,315 ÷ 4 = 25,601,578.75
If the quotient is a whole number, then 4 and 25,601,578.75 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 | 102,406,315 | |
| -1 | 102,406,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 41 | 55 | 205 | 451 | 2,255 | 45,413 | 227,065 | 499,543 | 1,861,933 | 2,497,715 | 9,309,665 | 20,481,263 | 102,406,315 |
| -1 | -5 | -11 | -41 | -55 | -205 | -451 | -2,255 | -45,413 | -227,065 | -499,543 | -1,861,933 | -2,497,715 | -9,309,665 | -20,481,263 | -102,406,315 |
