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 133,143,241, 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 | 133,143,241 | |
| -1 | -133,143,241 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 133,143,241.
Example:
1 x 133,143,241 = 133,143,241
and
-1 x -133,143,241 = 133,143,241
Notice both answers equal 133,143,241
With that explanation out of the way, let's continue. Next, we take the number 133,143,241 and divide it by 2:
133,143,241 ÷ 2 = 66,571,620.5
If the quotient is a whole number, then 2 and 66,571,620.5 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 | 133,143,241 | |
| -1 | -133,143,241 |
Now, we try dividing 133,143,241 by 3:
133,143,241 ÷ 3 = 44,381,080.3333
If the quotient is a whole number, then 3 and 44,381,080.3333 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 | 133,143,241 | |
| -1 | -133,143,241 |
Let's try dividing by 4:
133,143,241 ÷ 4 = 33,285,810.25
If the quotient is a whole number, then 4 and 33,285,810.25 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 | 133,143,241 | |
| -1 | 133,143,241 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 19 | 49 | 77 | 133 | 209 | 539 | 931 | 1,463 | 10,241 | 13,001 | 91,007 | 143,011 | 247,019 | 637,049 | 1,001,077 | 1,729,133 | 2,717,209 | 7,007,539 | 12,103,931 | 19,020,463 | 133,143,241 |
| -1 | -7 | -11 | -19 | -49 | -77 | -133 | -209 | -539 | -931 | -1,463 | -10,241 | -13,001 | -91,007 | -143,011 | -247,019 | -637,049 | -1,001,077 | -1,729,133 | -2,717,209 | -7,007,539 | -12,103,931 | -19,020,463 | -133,143,241 |
