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 321,010,135, 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 | 321,010,135 | |
| -1 | -321,010,135 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 321,010,135.
Example:
1 x 321,010,135 = 321,010,135
and
-1 x -321,010,135 = 321,010,135
Notice both answers equal 321,010,135
With that explanation out of the way, let's continue. Next, we take the number 321,010,135 and divide it by 2:
321,010,135 ÷ 2 = 160,505,067.5
If the quotient is a whole number, then 2 and 160,505,067.5 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 | 321,010,135 | |
| -1 | -321,010,135 |
Now, we try dividing 321,010,135 by 3:
321,010,135 ÷ 3 = 107,003,378.3333
If the quotient is a whole number, then 3 and 107,003,378.3333 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 | 321,010,135 | |
| -1 | -321,010,135 |
Let's try dividing by 4:
321,010,135 ÷ 4 = 80,252,533.75
If the quotient is a whole number, then 4 and 80,252,533.75 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 | 321,010,135 | |
| -1 | 321,010,135 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 53 | 145 | 265 | 1,537 | 7,685 | 41,771 | 208,855 | 1,211,359 | 2,213,863 | 6,056,795 | 11,069,315 | 64,202,027 | 321,010,135 |
| -1 | -5 | -29 | -53 | -145 | -265 | -1,537 | -7,685 | -41,771 | -208,855 | -1,211,359 | -2,213,863 | -6,056,795 | -11,069,315 | -64,202,027 | -321,010,135 |
