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 3,077,255, 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 | 3,077,255 | |
| -1 | -3,077,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,077,255.
Example:
1 x 3,077,255 = 3,077,255
and
-1 x -3,077,255 = 3,077,255
Notice both answers equal 3,077,255
With that explanation out of the way, let's continue. Next, we take the number 3,077,255 and divide it by 2:
3,077,255 ÷ 2 = 1,538,627.5
If the quotient is a whole number, then 2 and 1,538,627.5 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 | 3,077,255 | |
| -1 | -3,077,255 |
Now, we try dividing 3,077,255 by 3:
3,077,255 ÷ 3 = 1,025,751.6667
If the quotient is a whole number, then 3 and 1,025,751.6667 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 | 3,077,255 | |
| -1 | -3,077,255 |
Let's try dividing by 4:
3,077,255 ÷ 4 = 769,313.75
If the quotient is a whole number, then 4 and 769,313.75 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 | 3,077,255 | |
| -1 | 3,077,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 41 | 85 | 205 | 697 | 883 | 3,485 | 4,415 | 15,011 | 36,203 | 75,055 | 181,015 | 615,451 | 3,077,255 |
| -1 | -5 | -17 | -41 | -85 | -205 | -697 | -883 | -3,485 | -4,415 | -15,011 | -36,203 | -75,055 | -181,015 | -615,451 | -3,077,255 |
