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 135,717,127, 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 | 135,717,127 | |
| -1 | -135,717,127 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 135,717,127.
Example:
1 x 135,717,127 = 135,717,127
and
-1 x -135,717,127 = 135,717,127
Notice both answers equal 135,717,127
With that explanation out of the way, let's continue. Next, we take the number 135,717,127 and divide it by 2:
135,717,127 ÷ 2 = 67,858,563.5
If the quotient is a whole number, then 2 and 67,858,563.5 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 | 135,717,127 | |
| -1 | -135,717,127 |
Now, we try dividing 135,717,127 by 3:
135,717,127 ÷ 3 = 45,239,042.3333
If the quotient is a whole number, then 3 and 45,239,042.3333 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 | 135,717,127 | |
| -1 | -135,717,127 |
Let's try dividing by 4:
135,717,127 ÷ 4 = 33,929,281.75
If the quotient is a whole number, then 4 and 33,929,281.75 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 | 135,717,127 | |
| -1 | 135,717,127 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 1,091 | 1,367 | 7,637 | 9,569 | 14,183 | 17,771 | 99,281 | 124,397 | 1,491,397 | 10,439,779 | 19,388,161 | 135,717,127 |
| -1 | -7 | -13 | -91 | -1,091 | -1,367 | -7,637 | -9,569 | -14,183 | -17,771 | -99,281 | -124,397 | -1,491,397 | -10,439,779 | -19,388,161 | -135,717,127 |
