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 3,077,459, 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 | 3,077,459 | |
| -1 | -3,077,459 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,077,459.
Example:
1 x 3,077,459 = 3,077,459
and
-1 x -3,077,459 = 3,077,459
Notice both answers equal 3,077,459
With that explanation out of the way, let's continue. Next, we take the number 3,077,459 and divide it by 2:
3,077,459 ÷ 2 = 1,538,729.5
If the quotient is a whole number, then 2 and 1,538,729.5 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 | 3,077,459 | |
| -1 | -3,077,459 |
Now, we try dividing 3,077,459 by 3:
3,077,459 ÷ 3 = 1,025,819.6667
If the quotient is a whole number, then 3 and 1,025,819.6667 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 | 3,077,459 | |
| -1 | -3,077,459 |
Let's try dividing by 4:
3,077,459 ÷ 4 = 769,364.75
If the quotient is a whole number, then 4 and 769,364.75 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 | 3,077,459 | |
| -1 | 3,077,459 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 17 | 77 | 119 | 187 | 1,309 | 2,351 | 16,457 | 25,861 | 39,967 | 181,027 | 279,769 | 439,637 | 3,077,459 |
| -1 | -7 | -11 | -17 | -77 | -119 | -187 | -1,309 | -2,351 | -16,457 | -25,861 | -39,967 | -181,027 | -279,769 | -439,637 | -3,077,459 |
