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 133,251,433, 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 | 133,251,433 | |
| -1 | -133,251,433 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 133,251,433.
Example:
1 x 133,251,433 = 133,251,433
and
-1 x -133,251,433 = 133,251,433
Notice both answers equal 133,251,433
With that explanation out of the way, let's continue. Next, we take the number 133,251,433 and divide it by 2:
133,251,433 ÷ 2 = 66,625,716.5
If the quotient is a whole number, then 2 and 66,625,716.5 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 | 133,251,433 | |
| -1 | -133,251,433 |
Now, we try dividing 133,251,433 by 3:
133,251,433 ÷ 3 = 44,417,144.3333
If the quotient is a whole number, then 3 and 44,417,144.3333 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 | 133,251,433 | |
| -1 | -133,251,433 |
Let's try dividing by 4:
133,251,433 ÷ 4 = 33,312,858.25
If the quotient is a whole number, then 4 and 33,312,858.25 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 | 133,251,433 | |
| -1 | 133,251,433 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 49 | 79 | 203 | 553 | 1,187 | 1,421 | 2,291 | 3,871 | 8,309 | 16,037 | 34,423 | 58,163 | 93,773 | 112,259 | 240,961 | 656,411 | 1,686,727 | 2,719,417 | 4,594,877 | 19,035,919 | 133,251,433 |
| -1 | -7 | -29 | -49 | -79 | -203 | -553 | -1,187 | -1,421 | -2,291 | -3,871 | -8,309 | -16,037 | -34,423 | -58,163 | -93,773 | -112,259 | -240,961 | -656,411 | -1,686,727 | -2,719,417 | -4,594,877 | -19,035,919 | -133,251,433 |
