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 68,062,709, 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 | 68,062,709 | |
| -1 | -68,062,709 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 68,062,709.
Example:
1 x 68,062,709 = 68,062,709
and
-1 x -68,062,709 = 68,062,709
Notice both answers equal 68,062,709
With that explanation out of the way, let's continue. Next, we take the number 68,062,709 and divide it by 2:
68,062,709 ÷ 2 = 34,031,354.5
If the quotient is a whole number, then 2 and 34,031,354.5 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 | 68,062,709 | |
| -1 | -68,062,709 |
Now, we try dividing 68,062,709 by 3:
68,062,709 ÷ 3 = 22,687,569.6667
If the quotient is a whole number, then 3 and 22,687,569.6667 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 | 68,062,709 | |
| -1 | -68,062,709 |
Let's try dividing by 4:
68,062,709 ÷ 4 = 17,015,677.25
If the quotient is a whole number, then 4 and 17,015,677.25 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 | 68,062,709 | |
| -1 | 68,062,709 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 103 | 143 | 1,133 | 1,339 | 4,621 | 14,729 | 50,831 | 60,073 | 475,963 | 660,803 | 5,235,593 | 6,187,519 | 68,062,709 |
| -1 | -11 | -13 | -103 | -143 | -1,133 | -1,339 | -4,621 | -14,729 | -50,831 | -60,073 | -475,963 | -660,803 | -5,235,593 | -6,187,519 | -68,062,709 |
