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 320,255,335, 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 | 320,255,335 | |
| -1 | -320,255,335 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 320,255,335.
Example:
1 x 320,255,335 = 320,255,335
and
-1 x -320,255,335 = 320,255,335
Notice both answers equal 320,255,335
With that explanation out of the way, let's continue. Next, we take the number 320,255,335 and divide it by 2:
320,255,335 ÷ 2 = 160,127,667.5
If the quotient is a whole number, then 2 and 160,127,667.5 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 | 320,255,335 | |
| -1 | -320,255,335 |
Now, we try dividing 320,255,335 by 3:
320,255,335 ÷ 3 = 106,751,778.3333
If the quotient is a whole number, then 3 and 106,751,778.3333 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 | 320,255,335 | |
| -1 | -320,255,335 |
Let's try dividing by 4:
320,255,335 ÷ 4 = 80,063,833.75
If the quotient is a whole number, then 4 and 80,063,833.75 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 | 320,255,335 | |
| -1 | 320,255,335 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 79 | 115 | 395 | 1,817 | 9,085 | 35,251 | 176,255 | 810,773 | 2,784,829 | 4,053,865 | 13,924,145 | 64,051,067 | 320,255,335 |
| -1 | -5 | -23 | -79 | -115 | -395 | -1,817 | -9,085 | -35,251 | -176,255 | -810,773 | -2,784,829 | -4,053,865 | -13,924,145 | -64,051,067 | -320,255,335 |
