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 67,356,685, 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 | 67,356,685 | |
| -1 | -67,356,685 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 67,356,685.
Example:
1 x 67,356,685 = 67,356,685
and
-1 x -67,356,685 = 67,356,685
Notice both answers equal 67,356,685
With that explanation out of the way, let's continue. Next, we take the number 67,356,685 and divide it by 2:
67,356,685 ÷ 2 = 33,678,342.5
If the quotient is a whole number, then 2 and 33,678,342.5 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 | 67,356,685 | |
| -1 | -67,356,685 |
Now, we try dividing 67,356,685 by 3:
67,356,685 ÷ 3 = 22,452,228.3333
If the quotient is a whole number, then 3 and 22,452,228.3333 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 | 67,356,685 | |
| -1 | -67,356,685 |
Let's try dividing by 4:
67,356,685 ÷ 4 = 16,839,171.25
If the quotient is a whole number, then 4 and 16,839,171.25 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 | 67,356,685 | |
| -1 | 67,356,685 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 173 | 865 | 1,903 | 7,079 | 9,515 | 35,395 | 77,869 | 389,345 | 1,224,667 | 6,123,335 | 13,471,337 | 67,356,685 |
| -1 | -5 | -11 | -55 | -173 | -865 | -1,903 | -7,079 | -9,515 | -35,395 | -77,869 | -389,345 | -1,224,667 | -6,123,335 | -13,471,337 | -67,356,685 |
