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 102,343,315, 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 | 102,343,315 | |
| -1 | -102,343,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 102,343,315.
Example:
1 x 102,343,315 = 102,343,315
and
-1 x -102,343,315 = 102,343,315
Notice both answers equal 102,343,315
With that explanation out of the way, let's continue. Next, we take the number 102,343,315 and divide it by 2:
102,343,315 ÷ 2 = 51,171,657.5
If the quotient is a whole number, then 2 and 51,171,657.5 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 | 102,343,315 | |
| -1 | -102,343,315 |
Now, we try dividing 102,343,315 by 3:
102,343,315 ÷ 3 = 34,114,438.3333
If the quotient is a whole number, then 3 and 34,114,438.3333 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 | 102,343,315 | |
| -1 | -102,343,315 |
Let's try dividing by 4:
102,343,315 ÷ 4 = 25,585,828.75
If the quotient is a whole number, then 4 and 25,585,828.75 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 | 102,343,315 | |
| -1 | 102,343,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 79 | 85 | 395 | 1,343 | 6,715 | 15,241 | 76,205 | 259,097 | 1,204,039 | 1,295,485 | 6,020,195 | 20,468,663 | 102,343,315 |
| -1 | -5 | -17 | -79 | -85 | -395 | -1,343 | -6,715 | -15,241 | -76,205 | -259,097 | -1,204,039 | -1,295,485 | -6,020,195 | -20,468,663 | -102,343,315 |
