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 133,251,503, 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 | 133,251,503 | |
| -1 | -133,251,503 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 133,251,503.
Example:
1 x 133,251,503 = 133,251,503
and
-1 x -133,251,503 = 133,251,503
Notice both answers equal 133,251,503
With that explanation out of the way, let's continue. Next, we take the number 133,251,503 and divide it by 2:
133,251,503 ÷ 2 = 66,625,751.5
If the quotient is a whole number, then 2 and 66,625,751.5 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 | 133,251,503 | |
| -1 | -133,251,503 |
Now, we try dividing 133,251,503 by 3:
133,251,503 ÷ 3 = 44,417,167.6667
If the quotient is a whole number, then 3 and 44,417,167.6667 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 | 133,251,503 | |
| -1 | -133,251,503 |
Let's try dividing by 4:
133,251,503 ÷ 4 = 33,312,875.75
If the quotient is a whole number, then 4 and 33,312,875.75 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 | 133,251,503 | |
| -1 | 133,251,503 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 19 | 77 | 133 | 209 | 1,463 | 91,081 | 637,567 | 1,001,891 | 1,730,539 | 7,013,237 | 12,113,773 | 19,035,929 | 133,251,503 |
| -1 | -7 | -11 | -19 | -77 | -133 | -209 | -1,463 | -91,081 | -637,567 | -1,001,891 | -1,730,539 | -7,013,237 | -12,113,773 | -19,035,929 | -133,251,503 |
