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 133,002,331, 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 | 133,002,331 | |
| -1 | -133,002,331 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 133,002,331.
Example:
1 x 133,002,331 = 133,002,331
and
-1 x -133,002,331 = 133,002,331
Notice both answers equal 133,002,331
With that explanation out of the way, let's continue. Next, we take the number 133,002,331 and divide it by 2:
133,002,331 ÷ 2 = 66,501,165.5
If the quotient is a whole number, then 2 and 66,501,165.5 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 | 133,002,331 | |
| -1 | -133,002,331 |
Now, we try dividing 133,002,331 by 3:
133,002,331 ÷ 3 = 44,334,110.3333
If the quotient is a whole number, then 3 and 44,334,110.3333 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 | 133,002,331 | |
| -1 | -133,002,331 |
Let's try dividing by 4:
133,002,331 ÷ 4 = 33,250,582.75
If the quotient is a whole number, then 4 and 33,250,582.75 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 | 133,002,331 | |
| -1 | 133,002,331 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 449 | 3,143 | 3,847 | 4,939 | 26,929 | 34,573 | 42,317 | 296,219 | 1,727,303 | 12,091,121 | 19,000,333 | 133,002,331 |
| -1 | -7 | -11 | -77 | -449 | -3,143 | -3,847 | -4,939 | -26,929 | -34,573 | -42,317 | -296,219 | -1,727,303 | -12,091,121 | -19,000,333 | -133,002,331 |
