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 363,216,611, 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 | 363,216,611 | |
| -1 | -363,216,611 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 363,216,611.
Example:
1 x 363,216,611 = 363,216,611
and
-1 x -363,216,611 = 363,216,611
Notice both answers equal 363,216,611
With that explanation out of the way, let's continue. Next, we take the number 363,216,611 and divide it by 2:
363,216,611 ÷ 2 = 181,608,305.5
If the quotient is a whole number, then 2 and 181,608,305.5 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 | 363,216,611 | |
| -1 | -363,216,611 |
Now, we try dividing 363,216,611 by 3:
363,216,611 ÷ 3 = 121,072,203.6667
If the quotient is a whole number, then 3 and 121,072,203.6667 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 | 363,216,611 | |
| -1 | -363,216,611 |
Let's try dividing by 4:
363,216,611 ÷ 4 = 90,804,152.75
If the quotient is a whole number, then 4 and 90,804,152.75 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 | 363,216,611 | |
| -1 | 363,216,611 |
If you did it right, you will end up with this table:
| 1 | 17 | 47 | 499 | 799 | 911 | 8,483 | 15,487 | 23,453 | 42,817 | 398,701 | 454,589 | 727,889 | 7,728,013 | 21,365,683 | 363,216,611 |
| -1 | -17 | -47 | -499 | -799 | -911 | -8,483 | -15,487 | -23,453 | -42,817 | -398,701 | -454,589 | -727,889 | -7,728,013 | -21,365,683 | -363,216,611 |
