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 135,245,033, 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 | 135,245,033 | |
| -1 | -135,245,033 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 135,245,033.
Example:
1 x 135,245,033 = 135,245,033
and
-1 x -135,245,033 = 135,245,033
Notice both answers equal 135,245,033
With that explanation out of the way, let's continue. Next, we take the number 135,245,033 and divide it by 2:
135,245,033 ÷ 2 = 67,622,516.5
If the quotient is a whole number, then 2 and 67,622,516.5 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 | 135,245,033 | |
| -1 | -135,245,033 |
Now, we try dividing 135,245,033 by 3:
135,245,033 ÷ 3 = 45,081,677.6667
If the quotient is a whole number, then 3 and 45,081,677.6667 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 | 135,245,033 | |
| -1 | -135,245,033 |
Let's try dividing by 4:
135,245,033 ÷ 4 = 33,811,258.25
If the quotient is a whole number, then 4 and 33,811,258.25 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 | 135,245,033 | |
| -1 | 135,245,033 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 31 | 77 | 217 | 341 | 2,387 | 56,659 | 396,613 | 623,249 | 1,756,429 | 4,362,743 | 12,295,003 | 19,320,719 | 135,245,033 |
| -1 | -7 | -11 | -31 | -77 | -217 | -341 | -2,387 | -56,659 | -396,613 | -623,249 | -1,756,429 | -4,362,743 | -12,295,003 | -19,320,719 | -135,245,033 |
