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 135,435,443, 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 | 135,435,443 | |
| -1 | -135,435,443 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 135,435,443.
Example:
1 x 135,435,443 = 135,435,443
and
-1 x -135,435,443 = 135,435,443
Notice both answers equal 135,435,443
With that explanation out of the way, let's continue. Next, we take the number 135,435,443 and divide it by 2:
135,435,443 ÷ 2 = 67,717,721.5
If the quotient is a whole number, then 2 and 67,717,721.5 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 | 135,435,443 | |
| -1 | -135,435,443 |
Now, we try dividing 135,435,443 by 3:
135,435,443 ÷ 3 = 45,145,147.6667
If the quotient is a whole number, then 3 and 45,145,147.6667 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 | 135,435,443 | |
| -1 | -135,435,443 |
Let's try dividing by 4:
135,435,443 ÷ 4 = 33,858,860.75
If the quotient is a whole number, then 4 and 33,858,860.75 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 | 135,435,443 | |
| -1 | 135,435,443 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 109 | 143 | 1,199 | 1,417 | 8,689 | 15,587 | 95,579 | 112,957 | 947,101 | 1,242,527 | 10,418,111 | 12,312,313 | 135,435,443 |
| -1 | -11 | -13 | -109 | -143 | -1,199 | -1,417 | -8,689 | -15,587 | -95,579 | -112,957 | -947,101 | -1,242,527 | -10,418,111 | -12,312,313 | -135,435,443 |
