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 334,101,221, 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 | 334,101,221 | |
| -1 | -334,101,221 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 334,101,221.
Example:
1 x 334,101,221 = 334,101,221
and
-1 x -334,101,221 = 334,101,221
Notice both answers equal 334,101,221
With that explanation out of the way, let's continue. Next, we take the number 334,101,221 and divide it by 2:
334,101,221 ÷ 2 = 167,050,610.5
If the quotient is a whole number, then 2 and 167,050,610.5 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 | 334,101,221 | |
| -1 | -334,101,221 |
Now, we try dividing 334,101,221 by 3:
334,101,221 ÷ 3 = 111,367,073.6667
If the quotient is a whole number, then 3 and 111,367,073.6667 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 | 334,101,221 | |
| -1 | -334,101,221 |
Let's try dividing by 4:
334,101,221 ÷ 4 = 83,525,305.25
If the quotient is a whole number, then 4 and 83,525,305.25 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 | 334,101,221 | |
| -1 | 334,101,221 |
If you did it right, you will end up with this table:
| 1 | 17 | 71 | 131 | 1,207 | 2,113 | 2,227 | 9,301 | 35,921 | 150,023 | 158,117 | 276,803 | 2,550,391 | 4,705,651 | 19,653,013 | 334,101,221 |
| -1 | -17 | -71 | -131 | -1,207 | -2,113 | -2,227 | -9,301 | -35,921 | -150,023 | -158,117 | -276,803 | -2,550,391 | -4,705,651 | -19,653,013 | -334,101,221 |
