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 133,102,505, 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 | 133,102,505 | |
| -1 | -133,102,505 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 133,102,505.
Example:
1 x 133,102,505 = 133,102,505
and
-1 x -133,102,505 = 133,102,505
Notice both answers equal 133,102,505
With that explanation out of the way, let's continue. Next, we take the number 133,102,505 and divide it by 2:
133,102,505 ÷ 2 = 66,551,252.5
If the quotient is a whole number, then 2 and 66,551,252.5 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 | 133,102,505 | |
| -1 | -133,102,505 |
Now, we try dividing 133,102,505 by 3:
133,102,505 ÷ 3 = 44,367,501.6667
If the quotient is a whole number, then 3 and 44,367,501.6667 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 | 133,102,505 | |
| -1 | -133,102,505 |
Let's try dividing by 4:
133,102,505 ÷ 4 = 33,275,626.25
If the quotient is a whole number, then 4 and 33,275,626.25 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 | 133,102,505 | |
| -1 | 133,102,505 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 37 | 95 | 185 | 361 | 703 | 1,805 | 1,993 | 3,515 | 9,965 | 13,357 | 37,867 | 66,785 | 73,741 | 189,335 | 368,705 | 719,473 | 1,401,079 | 3,597,365 | 7,005,395 | 26,620,501 | 133,102,505 |
| -1 | -5 | -19 | -37 | -95 | -185 | -361 | -703 | -1,805 | -1,993 | -3,515 | -9,965 | -13,357 | -37,867 | -66,785 | -73,741 | -189,335 | -368,705 | -719,473 | -1,401,079 | -3,597,365 | -7,005,395 | -26,620,501 | -133,102,505 |
