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 135,712,411, 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 | 135,712,411 | |
| -1 | -135,712,411 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 135,712,411.
Example:
1 x 135,712,411 = 135,712,411
and
-1 x -135,712,411 = 135,712,411
Notice both answers equal 135,712,411
With that explanation out of the way, let's continue. Next, we take the number 135,712,411 and divide it by 2:
135,712,411 ÷ 2 = 67,856,205.5
If the quotient is a whole number, then 2 and 67,856,205.5 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 | 135,712,411 | |
| -1 | -135,712,411 |
Now, we try dividing 135,712,411 by 3:
135,712,411 ÷ 3 = 45,237,470.3333
If the quotient is a whole number, then 3 and 45,237,470.3333 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 | 135,712,411 | |
| -1 | -135,712,411 |
Let's try dividing by 4:
135,712,411 ÷ 4 = 33,928,102.75
If the quotient is a whole number, then 4 and 33,928,102.75 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 | 135,712,411 | |
| -1 | 135,712,411 |
If you did it right, you will end up with this table:
| 1 | 17 | 37 | 359 | 601 | 629 | 6,103 | 10,217 | 13,283 | 22,237 | 215,759 | 225,811 | 378,029 | 3,667,903 | 7,983,083 | 135,712,411 |
| -1 | -17 | -37 | -359 | -601 | -629 | -6,103 | -10,217 | -13,283 | -22,237 | -215,759 | -225,811 | -378,029 | -3,667,903 | -7,983,083 | -135,712,411 |
