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 133,324,505, 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 | 133,324,505 | |
| -1 | -133,324,505 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 133,324,505.
Example:
1 x 133,324,505 = 133,324,505
and
-1 x -133,324,505 = 133,324,505
Notice both answers equal 133,324,505
With that explanation out of the way, let's continue. Next, we take the number 133,324,505 and divide it by 2:
133,324,505 ÷ 2 = 66,662,252.5
If the quotient is a whole number, then 2 and 66,662,252.5 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 | 133,324,505 | |
| -1 | -133,324,505 |
Now, we try dividing 133,324,505 by 3:
133,324,505 ÷ 3 = 44,441,501.6667
If the quotient is a whole number, then 3 and 44,441,501.6667 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 | 133,324,505 | |
| -1 | -133,324,505 |
Let's try dividing by 4:
133,324,505 ÷ 4 = 33,331,126.25
If the quotient is a whole number, then 4 and 33,331,126.25 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 | 133,324,505 | |
| -1 | 133,324,505 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 185 | 577 | 1,249 | 2,885 | 6,245 | 21,349 | 46,213 | 106,745 | 231,065 | 720,673 | 3,603,365 | 26,664,901 | 133,324,505 |
| -1 | -5 | -37 | -185 | -577 | -1,249 | -2,885 | -6,245 | -21,349 | -46,213 | -106,745 | -231,065 | -720,673 | -3,603,365 | -26,664,901 | -133,324,505 |
