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 135,202,045, 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 | 135,202,045 | |
| -1 | -135,202,045 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 135,202,045.
Example:
1 x 135,202,045 = 135,202,045
and
-1 x -135,202,045 = 135,202,045
Notice both answers equal 135,202,045
With that explanation out of the way, let's continue. Next, we take the number 135,202,045 and divide it by 2:
135,202,045 ÷ 2 = 67,601,022.5
If the quotient is a whole number, then 2 and 67,601,022.5 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 | 135,202,045 | |
| -1 | -135,202,045 |
Now, we try dividing 135,202,045 by 3:
135,202,045 ÷ 3 = 45,067,348.3333
If the quotient is a whole number, then 3 and 45,067,348.3333 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 | 135,202,045 | |
| -1 | -135,202,045 |
Let's try dividing by 4:
135,202,045 ÷ 4 = 33,800,511.25
If the quotient is a whole number, then 4 and 33,800,511.25 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 | 135,202,045 | |
| -1 | 135,202,045 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 421 | 2,105 | 4,631 | 5,839 | 23,155 | 29,195 | 64,229 | 321,145 | 2,458,219 | 12,291,095 | 27,040,409 | 135,202,045 |
| -1 | -5 | -11 | -55 | -421 | -2,105 | -4,631 | -5,839 | -23,155 | -29,195 | -64,229 | -321,145 | -2,458,219 | -12,291,095 | -27,040,409 | -135,202,045 |
