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 135,775,367, 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 | 135,775,367 | |
| -1 | -135,775,367 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 135,775,367.
Example:
1 x 135,775,367 = 135,775,367
and
-1 x -135,775,367 = 135,775,367
Notice both answers equal 135,775,367
With that explanation out of the way, let's continue. Next, we take the number 135,775,367 and divide it by 2:
135,775,367 ÷ 2 = 67,887,683.5
If the quotient is a whole number, then 2 and 67,887,683.5 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 | 135,775,367 | |
| -1 | -135,775,367 |
Now, we try dividing 135,775,367 by 3:
135,775,367 ÷ 3 = 45,258,455.6667
If the quotient is a whole number, then 3 and 45,258,455.6667 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 | 135,775,367 | |
| -1 | -135,775,367 |
Let's try dividing by 4:
135,775,367 ÷ 4 = 33,943,841.75
If the quotient is a whole number, then 4 and 33,943,841.75 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 | 135,775,367 | |
| -1 | 135,775,367 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 857 | 1,741 | 5,999 | 11,141 | 12,187 | 22,633 | 77,987 | 158,431 | 1,492,037 | 10,444,259 | 19,396,481 | 135,775,367 |
| -1 | -7 | -13 | -91 | -857 | -1,741 | -5,999 | -11,141 | -12,187 | -22,633 | -77,987 | -158,431 | -1,492,037 | -10,444,259 | -19,396,481 | -135,775,367 |
