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 3,133,255, 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 | 3,133,255 | |
| -1 | -3,133,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,133,255.
Example:
1 x 3,133,255 = 3,133,255
and
-1 x -3,133,255 = 3,133,255
Notice both answers equal 3,133,255
With that explanation out of the way, let's continue. Next, we take the number 3,133,255 and divide it by 2:
3,133,255 ÷ 2 = 1,566,627.5
If the quotient is a whole number, then 2 and 1,566,627.5 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 | 3,133,255 | |
| -1 | -3,133,255 |
Now, we try dividing 3,133,255 by 3:
3,133,255 ÷ 3 = 1,044,418.3333
If the quotient is a whole number, then 3 and 1,044,418.3333 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 | 3,133,255 | |
| -1 | -3,133,255 |
Let's try dividing by 4:
3,133,255 ÷ 4 = 783,313.75
If the quotient is a whole number, then 4 and 783,313.75 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 | 3,133,255 | |
| -1 | 3,133,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 47 | 67 | 199 | 235 | 335 | 995 | 3,149 | 9,353 | 13,333 | 15,745 | 46,765 | 66,665 | 626,651 | 3,133,255 |
| -1 | -5 | -47 | -67 | -199 | -235 | -335 | -995 | -3,149 | -9,353 | -13,333 | -15,745 | -46,765 | -66,665 | -626,651 | -3,133,255 |
