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 68,085,227, 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 | 68,085,227 | |
| -1 | -68,085,227 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 68,085,227.
Example:
1 x 68,085,227 = 68,085,227
and
-1 x -68,085,227 = 68,085,227
Notice both answers equal 68,085,227
With that explanation out of the way, let's continue. Next, we take the number 68,085,227 and divide it by 2:
68,085,227 ÷ 2 = 34,042,613.5
If the quotient is a whole number, then 2 and 34,042,613.5 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 | 68,085,227 | |
| -1 | -68,085,227 |
Now, we try dividing 68,085,227 by 3:
68,085,227 ÷ 3 = 22,695,075.6667
If the quotient is a whole number, then 3 and 22,695,075.6667 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 | 68,085,227 | |
| -1 | -68,085,227 |
Let's try dividing by 4:
68,085,227 ÷ 4 = 17,021,306.75
If the quotient is a whole number, then 4 and 17,021,306.75 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 | 68,085,227 | |
| -1 | 68,085,227 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 133 | 271 | 1,889 | 1,897 | 5,149 | 13,223 | 35,891 | 36,043 | 251,237 | 511,919 | 3,583,433 | 9,726,461 | 68,085,227 |
| -1 | -7 | -19 | -133 | -271 | -1,889 | -1,897 | -5,149 | -13,223 | -35,891 | -36,043 | -251,237 | -511,919 | -3,583,433 | -9,726,461 | -68,085,227 |
