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 133,042,301, 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 | 133,042,301 | |
| -1 | -133,042,301 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 133,042,301.
Example:
1 x 133,042,301 = 133,042,301
and
-1 x -133,042,301 = 133,042,301
Notice both answers equal 133,042,301
With that explanation out of the way, let's continue. Next, we take the number 133,042,301 and divide it by 2:
133,042,301 ÷ 2 = 66,521,150.5
If the quotient is a whole number, then 2 and 66,521,150.5 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 | 133,042,301 | |
| -1 | -133,042,301 |
Now, we try dividing 133,042,301 by 3:
133,042,301 ÷ 3 = 44,347,433.6667
If the quotient is a whole number, then 3 and 44,347,433.6667 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 | 133,042,301 | |
| -1 | -133,042,301 |
Let's try dividing by 4:
133,042,301 ÷ 4 = 33,260,575.25
If the quotient is a whole number, then 4 and 33,260,575.25 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 | 133,042,301 | |
| -1 | 133,042,301 |
If you did it right, you will end up with this table:
| 1 | 7 | 43 | 49 | 233 | 271 | 301 | 1,631 | 1,897 | 2,107 | 10,019 | 11,417 | 11,653 | 13,279 | 63,143 | 70,133 | 81,571 | 442,001 | 490,931 | 570,997 | 2,715,149 | 3,094,007 | 19,006,043 | 133,042,301 |
| -1 | -7 | -43 | -49 | -233 | -271 | -301 | -1,631 | -1,897 | -2,107 | -10,019 | -11,417 | -11,653 | -13,279 | -63,143 | -70,133 | -81,571 | -442,001 | -490,931 | -570,997 | -2,715,149 | -3,094,007 | -19,006,043 | -133,042,301 |
