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 320,325,533, 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 | 320,325,533 | |
| -1 | -320,325,533 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 320,325,533.
Example:
1 x 320,325,533 = 320,325,533
and
-1 x -320,325,533 = 320,325,533
Notice both answers equal 320,325,533
With that explanation out of the way, let's continue. Next, we take the number 320,325,533 and divide it by 2:
320,325,533 ÷ 2 = 160,162,766.5
If the quotient is a whole number, then 2 and 160,162,766.5 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 | 320,325,533 | |
| -1 | -320,325,533 |
Now, we try dividing 320,325,533 by 3:
320,325,533 ÷ 3 = 106,775,177.6667
If the quotient is a whole number, then 3 and 106,775,177.6667 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 | 320,325,533 | |
| -1 | -320,325,533 |
Let's try dividing by 4:
320,325,533 ÷ 4 = 80,081,383.25
If the quotient is a whole number, then 4 and 80,081,383.25 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 | 320,325,533 | |
| -1 | 320,325,533 |
If you did it right, you will end up with this table:
| 1 | 11 | 43 | 73 | 473 | 803 | 3,139 | 9,277 | 34,529 | 102,047 | 398,911 | 677,221 | 4,388,021 | 7,449,431 | 29,120,503 | 320,325,533 |
| -1 | -11 | -43 | -73 | -473 | -803 | -3,139 | -9,277 | -34,529 | -102,047 | -398,911 | -677,221 | -4,388,021 | -7,449,431 | -29,120,503 | -320,325,533 |
