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 3,077,833, 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 | 3,077,833 | |
| -1 | -3,077,833 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,077,833.
Example:
1 x 3,077,833 = 3,077,833
and
-1 x -3,077,833 = 3,077,833
Notice both answers equal 3,077,833
With that explanation out of the way, let's continue. Next, we take the number 3,077,833 and divide it by 2:
3,077,833 ÷ 2 = 1,538,916.5
If the quotient is a whole number, then 2 and 1,538,916.5 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 | 3,077,833 | |
| -1 | -3,077,833 |
Now, we try dividing 3,077,833 by 3:
3,077,833 ÷ 3 = 1,025,944.3333
If the quotient is a whole number, then 3 and 1,025,944.3333 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 | 3,077,833 | |
| -1 | -3,077,833 |
Let's try dividing by 4:
3,077,833 ÷ 4 = 769,458.25
If the quotient is a whole number, then 4 and 769,458.25 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 | 3,077,833 | |
| -1 | 3,077,833 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 109 | 151 | 187 | 1,199 | 1,661 | 1,853 | 2,567 | 16,459 | 20,383 | 28,237 | 181,049 | 279,803 | 3,077,833 |
| -1 | -11 | -17 | -109 | -151 | -187 | -1,199 | -1,661 | -1,853 | -2,567 | -16,459 | -20,383 | -28,237 | -181,049 | -279,803 | -3,077,833 |
