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 68,579,063, 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 | 68,579,063 | |
| -1 | -68,579,063 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 68,579,063.
Example:
1 x 68,579,063 = 68,579,063
and
-1 x -68,579,063 = 68,579,063
Notice both answers equal 68,579,063
With that explanation out of the way, let's continue. Next, we take the number 68,579,063 and divide it by 2:
68,579,063 ÷ 2 = 34,289,531.5
If the quotient is a whole number, then 2 and 34,289,531.5 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 | 68,579,063 | |
| -1 | -68,579,063 |
Now, we try dividing 68,579,063 by 3:
68,579,063 ÷ 3 = 22,859,687.6667
If the quotient is a whole number, then 3 and 22,859,687.6667 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 | 68,579,063 | |
| -1 | -68,579,063 |
Let's try dividing by 4:
68,579,063 ÷ 4 = 17,144,765.75
If the quotient is a whole number, then 4 and 17,144,765.75 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 | 68,579,063 | |
| -1 | 68,579,063 |
If you did it right, you will end up with this table:
| 1 | 7 | 47 | 59 | 329 | 413 | 2,773 | 3,533 | 19,411 | 24,731 | 166,051 | 208,447 | 1,162,357 | 1,459,129 | 9,797,009 | 68,579,063 |
| -1 | -7 | -47 | -59 | -329 | -413 | -2,773 | -3,533 | -19,411 | -24,731 | -166,051 | -208,447 | -1,162,357 | -1,459,129 | -9,797,009 | -68,579,063 |
