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 67,247,135, 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 | 67,247,135 | |
| -1 | -67,247,135 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 67,247,135.
Example:
1 x 67,247,135 = 67,247,135
and
-1 x -67,247,135 = 67,247,135
Notice both answers equal 67,247,135
With that explanation out of the way, let's continue. Next, we take the number 67,247,135 and divide it by 2:
67,247,135 ÷ 2 = 33,623,567.5
If the quotient is a whole number, then 2 and 33,623,567.5 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 | 67,247,135 | |
| -1 | -67,247,135 |
Now, we try dividing 67,247,135 by 3:
67,247,135 ÷ 3 = 22,415,711.6667
If the quotient is a whole number, then 3 and 22,415,711.6667 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 | 67,247,135 | |
| -1 | -67,247,135 |
Let's try dividing by 4:
67,247,135 ÷ 4 = 16,811,783.75
If the quotient is a whole number, then 4 and 16,811,783.75 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 | 67,247,135 | |
| -1 | 67,247,135 |
If you did it right, you will end up with this table:
| 1 | 5 | 127 | 137 | 635 | 685 | 773 | 3,865 | 17,399 | 86,995 | 98,171 | 105,901 | 490,855 | 529,505 | 13,449,427 | 67,247,135 |
| -1 | -5 | -127 | -137 | -635 | -685 | -773 | -3,865 | -17,399 | -86,995 | -98,171 | -105,901 | -490,855 | -529,505 | -13,449,427 | -67,247,135 |
