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 68,635,697, 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 | 68,635,697 | |
| -1 | -68,635,697 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 68,635,697.
Example:
1 x 68,635,697 = 68,635,697
and
-1 x -68,635,697 = 68,635,697
Notice both answers equal 68,635,697
With that explanation out of the way, let's continue. Next, we take the number 68,635,697 and divide it by 2:
68,635,697 ÷ 2 = 34,317,848.5
If the quotient is a whole number, then 2 and 34,317,848.5 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 | 68,635,697 | |
| -1 | -68,635,697 |
Now, we try dividing 68,635,697 by 3:
68,635,697 ÷ 3 = 22,878,565.6667
If the quotient is a whole number, then 3 and 22,878,565.6667 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 | 68,635,697 | |
| -1 | -68,635,697 |
Let's try dividing by 4:
68,635,697 ÷ 4 = 17,158,924.25
If the quotient is a whole number, then 4 and 17,158,924.25 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 | 68,635,697 | |
| -1 | 68,635,697 |
If you did it right, you will end up with this table:
| 1 | 13 | 43 | 199 | 559 | 617 | 2,587 | 8,021 | 8,557 | 26,531 | 111,241 | 122,783 | 344,903 | 1,596,179 | 5,279,669 | 68,635,697 |
| -1 | -13 | -43 | -199 | -559 | -617 | -2,587 | -8,021 | -8,557 | -26,531 | -111,241 | -122,783 | -344,903 | -1,596,179 | -5,279,669 | -68,635,697 |
