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 68,350,009, 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 | 68,350,009 | |
| -1 | -68,350,009 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 68,350,009.
Example:
1 x 68,350,009 = 68,350,009
and
-1 x -68,350,009 = 68,350,009
Notice both answers equal 68,350,009
With that explanation out of the way, let's continue. Next, we take the number 68,350,009 and divide it by 2:
68,350,009 ÷ 2 = 34,175,004.5
If the quotient is a whole number, then 2 and 34,175,004.5 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 | 68,350,009 | |
| -1 | -68,350,009 |
Now, we try dividing 68,350,009 by 3:
68,350,009 ÷ 3 = 22,783,336.3333
If the quotient is a whole number, then 3 and 22,783,336.3333 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 | 68,350,009 | |
| -1 | -68,350,009 |
Let's try dividing by 4:
68,350,009 ÷ 4 = 17,087,502.25
If the quotient is a whole number, then 4 and 17,087,502.25 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 | 68,350,009 | |
| -1 | 68,350,009 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 31 | 91 | 217 | 403 | 2,821 | 24,229 | 169,603 | 314,977 | 751,099 | 2,204,839 | 5,257,693 | 9,764,287 | 68,350,009 |
| -1 | -7 | -13 | -31 | -91 | -217 | -403 | -2,821 | -24,229 | -169,603 | -314,977 | -751,099 | -2,204,839 | -5,257,693 | -9,764,287 | -68,350,009 |
