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 3,075,709, 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 | 3,075,709 | |
| -1 | -3,075,709 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,075,709.
Example:
1 x 3,075,709 = 3,075,709
and
-1 x -3,075,709 = 3,075,709
Notice both answers equal 3,075,709
With that explanation out of the way, let's continue. Next, we take the number 3,075,709 and divide it by 2:
3,075,709 ÷ 2 = 1,537,854.5
If the quotient is a whole number, then 2 and 1,537,854.5 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 | 3,075,709 | |
| -1 | -3,075,709 |
Now, we try dividing 3,075,709 by 3:
3,075,709 ÷ 3 = 1,025,236.3333
If the quotient is a whole number, then 3 and 1,025,236.3333 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 | 3,075,709 | |
| -1 | -3,075,709 |
Let's try dividing by 4:
3,075,709 ÷ 4 = 768,927.25
If the quotient is a whole number, then 4 and 768,927.25 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 | 3,075,709 | |
| -1 | 3,075,709 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 73 | 91 | 463 | 511 | 949 | 3,241 | 6,019 | 6,643 | 33,799 | 42,133 | 236,593 | 439,387 | 3,075,709 |
| -1 | -7 | -13 | -73 | -91 | -463 | -511 | -949 | -3,241 | -6,019 | -6,643 | -33,799 | -42,133 | -236,593 | -439,387 | -3,075,709 |
