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 68,134,285, 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 | 68,134,285 | |
| -1 | -68,134,285 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 68,134,285.
Example:
1 x 68,134,285 = 68,134,285
and
-1 x -68,134,285 = 68,134,285
Notice both answers equal 68,134,285
With that explanation out of the way, let's continue. Next, we take the number 68,134,285 and divide it by 2:
68,134,285 ÷ 2 = 34,067,142.5
If the quotient is a whole number, then 2 and 34,067,142.5 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 | 68,134,285 | |
| -1 | -68,134,285 |
Now, we try dividing 68,134,285 by 3:
68,134,285 ÷ 3 = 22,711,428.3333
If the quotient is a whole number, then 3 and 22,711,428.3333 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 | 68,134,285 | |
| -1 | -68,134,285 |
Let's try dividing by 4:
68,134,285 ÷ 4 = 17,033,571.25
If the quotient is a whole number, then 4 and 17,033,571.25 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 | 68,134,285 | |
| -1 | 68,134,285 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 83 | 95 | 415 | 1,577 | 7,885 | 8,641 | 43,205 | 164,179 | 717,203 | 820,895 | 3,586,015 | 13,626,857 | 68,134,285 |
| -1 | -5 | -19 | -83 | -95 | -415 | -1,577 | -7,885 | -8,641 | -43,205 | -164,179 | -717,203 | -820,895 | -3,586,015 | -13,626,857 | -68,134,285 |
