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 335,554,121, 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 | 335,554,121 | |
| -1 | -335,554,121 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 335,554,121.
Example:
1 x 335,554,121 = 335,554,121
and
-1 x -335,554,121 = 335,554,121
Notice both answers equal 335,554,121
With that explanation out of the way, let's continue. Next, we take the number 335,554,121 and divide it by 2:
335,554,121 ÷ 2 = 167,777,060.5
If the quotient is a whole number, then 2 and 167,777,060.5 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 | 335,554,121 | |
| -1 | -335,554,121 |
Now, we try dividing 335,554,121 by 3:
335,554,121 ÷ 3 = 111,851,373.6667
If the quotient is a whole number, then 3 and 111,851,373.6667 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 | 335,554,121 | |
| -1 | -335,554,121 |
Let's try dividing by 4:
335,554,121 ÷ 4 = 83,888,530.25
If the quotient is a whole number, then 4 and 83,888,530.25 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 | 335,554,121 | |
| -1 | 335,554,121 |
If you did it right, you will end up with this table:
| 1 | 7 | 103 | 223 | 721 | 1,561 | 2,087 | 14,609 | 22,969 | 160,783 | 214,961 | 465,401 | 1,504,727 | 3,257,807 | 47,936,303 | 335,554,121 |
| -1 | -7 | -103 | -223 | -721 | -1,561 | -2,087 | -14,609 | -22,969 | -160,783 | -214,961 | -465,401 | -1,504,727 | -3,257,807 | -47,936,303 | -335,554,121 |
