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 133,233,337, 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 | 133,233,337 | |
| -1 | -133,233,337 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 133,233,337.
Example:
1 x 133,233,337 = 133,233,337
and
-1 x -133,233,337 = 133,233,337
Notice both answers equal 133,233,337
With that explanation out of the way, let's continue. Next, we take the number 133,233,337 and divide it by 2:
133,233,337 ÷ 2 = 66,616,668.5
If the quotient is a whole number, then 2 and 66,616,668.5 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 | 133,233,337 | |
| -1 | -133,233,337 |
Now, we try dividing 133,233,337 by 3:
133,233,337 ÷ 3 = 44,411,112.3333
If the quotient is a whole number, then 3 and 44,411,112.3333 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 | 133,233,337 | |
| -1 | -133,233,337 |
Let's try dividing by 4:
133,233,337 ÷ 4 = 33,308,334.25
If the quotient is a whole number, then 4 and 33,308,334.25 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 | 133,233,337 | |
| -1 | 133,233,337 |
If you did it right, you will end up with this table:
| 1 | 29 | 37 | 227 | 547 | 1,073 | 6,583 | 8,399 | 15,863 | 20,239 | 124,169 | 243,571 | 586,931 | 3,600,901 | 4,594,253 | 133,233,337 |
| -1 | -29 | -37 | -227 | -547 | -1,073 | -6,583 | -8,399 | -15,863 | -20,239 | -124,169 | -243,571 | -586,931 | -3,600,901 | -4,594,253 | -133,233,337 |
