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 302,173,255, 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 | 302,173,255 | |
| -1 | -302,173,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 302,173,255.
Example:
1 x 302,173,255 = 302,173,255
and
-1 x -302,173,255 = 302,173,255
Notice both answers equal 302,173,255
With that explanation out of the way, let's continue. Next, we take the number 302,173,255 and divide it by 2:
302,173,255 ÷ 2 = 151,086,627.5
If the quotient is a whole number, then 2 and 151,086,627.5 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 | 302,173,255 | |
| -1 | -302,173,255 |
Now, we try dividing 302,173,255 by 3:
302,173,255 ÷ 3 = 100,724,418.3333
If the quotient is a whole number, then 3 and 100,724,418.3333 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 | 302,173,255 | |
| -1 | -302,173,255 |
Let's try dividing by 4:
302,173,255 ÷ 4 = 75,543,313.75
If the quotient is a whole number, then 4 and 75,543,313.75 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 | 302,173,255 | |
| -1 | 302,173,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 43 | 215 | 389 | 1,945 | 3,613 | 16,727 | 18,065 | 83,635 | 155,359 | 776,795 | 1,405,457 | 7,027,285 | 60,434,651 | 302,173,255 |
| -1 | -5 | -43 | -215 | -389 | -1,945 | -3,613 | -16,727 | -18,065 | -83,635 | -155,359 | -776,795 | -1,405,457 | -7,027,285 | -60,434,651 | -302,173,255 |
