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 133,232,351, 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 | 133,232,351 | |
| -1 | -133,232,351 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 133,232,351.
Example:
1 x 133,232,351 = 133,232,351
and
-1 x -133,232,351 = 133,232,351
Notice both answers equal 133,232,351
With that explanation out of the way, let's continue. Next, we take the number 133,232,351 and divide it by 2:
133,232,351 ÷ 2 = 66,616,175.5
If the quotient is a whole number, then 2 and 66,616,175.5 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 | 133,232,351 | |
| -1 | -133,232,351 |
Now, we try dividing 133,232,351 by 3:
133,232,351 ÷ 3 = 44,410,783.6667
If the quotient is a whole number, then 3 and 44,410,783.6667 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 | 133,232,351 | |
| -1 | -133,232,351 |
Let's try dividing by 4:
133,232,351 ÷ 4 = 33,308,087.75
If the quotient is a whole number, then 4 and 33,308,087.75 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 | 133,232,351 | |
| -1 | 133,232,351 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 29 | 133 | 203 | 551 | 3,857 | 34,543 | 241,801 | 656,317 | 1,001,747 | 4,594,219 | 7,012,229 | 19,033,193 | 133,232,351 |
| -1 | -7 | -19 | -29 | -133 | -203 | -551 | -3,857 | -34,543 | -241,801 | -656,317 | -1,001,747 | -4,594,219 | -7,012,229 | -19,033,193 | -133,232,351 |
