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 135,555,563, 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 | 135,555,563 | |
| -1 | -135,555,563 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 135,555,563.
Example:
1 x 135,555,563 = 135,555,563
and
-1 x -135,555,563 = 135,555,563
Notice both answers equal 135,555,563
With that explanation out of the way, let's continue. Next, we take the number 135,555,563 and divide it by 2:
135,555,563 ÷ 2 = 67,777,781.5
If the quotient is a whole number, then 2 and 67,777,781.5 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 | 135,555,563 | |
| -1 | -135,555,563 |
Now, we try dividing 135,555,563 by 3:
135,555,563 ÷ 3 = 45,185,187.6667
If the quotient is a whole number, then 3 and 45,185,187.6667 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 | 135,555,563 | |
| -1 | -135,555,563 |
Let's try dividing by 4:
135,555,563 ÷ 4 = 33,888,890.75
If the quotient is a whole number, then 4 and 33,888,890.75 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 | 135,555,563 | |
| -1 | 135,555,563 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 143 | 479 | 1,979 | 5,269 | 6,227 | 21,769 | 25,727 | 68,497 | 282,997 | 947,941 | 10,427,351 | 12,323,233 | 135,555,563 |
| -1 | -11 | -13 | -143 | -479 | -1,979 | -5,269 | -6,227 | -21,769 | -25,727 | -68,497 | -282,997 | -947,941 | -10,427,351 | -12,323,233 | -135,555,563 |
