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 68,552,855, 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 | 68,552,855 | |
| -1 | -68,552,855 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 68,552,855.
Example:
1 x 68,552,855 = 68,552,855
and
-1 x -68,552,855 = 68,552,855
Notice both answers equal 68,552,855
With that explanation out of the way, let's continue. Next, we take the number 68,552,855 and divide it by 2:
68,552,855 ÷ 2 = 34,276,427.5
If the quotient is a whole number, then 2 and 34,276,427.5 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 | 68,552,855 | |
| -1 | -68,552,855 |
Now, we try dividing 68,552,855 by 3:
68,552,855 ÷ 3 = 22,850,951.6667
If the quotient is a whole number, then 3 and 22,850,951.6667 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 | 68,552,855 | |
| -1 | -68,552,855 |
Let's try dividing by 4:
68,552,855 ÷ 4 = 17,138,213.75
If the quotient is a whole number, then 4 and 17,138,213.75 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 | 68,552,855 | |
| -1 | 68,552,855 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 19 | 35 | 95 | 133 | 665 | 103,087 | 515,435 | 721,609 | 1,958,653 | 3,608,045 | 9,793,265 | 13,710,571 | 68,552,855 |
| -1 | -5 | -7 | -19 | -35 | -95 | -133 | -665 | -103,087 | -515,435 | -721,609 | -1,958,653 | -3,608,045 | -9,793,265 | -13,710,571 | -68,552,855 |
